ICE3PCS01GXUMA1 Overview
A Power Factor Correction (PFC) controller is a specialized power management IC that shapes the input current drawn from the AC mains to be in phase with the input voltage, achieving a power factor close to unity (typically >0.99). PFC controllers sit in the power management hierarchy between the bridge rectifier and the bulk DC link capacitor in AC-DC power supplies; they are mandatory for switched-mode power supplies above 75 W to meet regulatory standards such as IEC 61000-3-2 and ENERGY STAR. CCM operation specifically means the boost inductor current never falls to zero during a switching cycle, which yields lower peak currents and lower EMI than critical conduction mode (CrCM/CRM) at high power levels above 300 W.
The ICE3PCS01GXUMA1 integrates a totem-pole gate driver capable of 1.5 A source / 2 A sink, an internal 2.5 V trimmed bandgap reference, soft-start control, under-voltage lockout, and over-current protection with a typical quiescent current of 1.4 mA. The cascaded control architecture implements an inner average-current loop and an outer voltage loop with digital compensation, eliminating the traditional RC component network. The device supports boost topologies commonly used in digital TV power supplies, industrial SMPS, and high-power LED drivers requiring PF >0.9 and low total harmonic distortion.
Typical applications include 100 W to 1000 W boost PFC front-end stages for ATX power supplies, flat-panel TV converters, e-bike chargers, industrial SMPS modules, and high-bay LED drivers. The wide 85-265 VAC input range makes it a single design platform for global products. Compared to the previous-generation ICE2PCS0x family, the third-generation ICE3PCS01G offers lower quiescent current, tighter reference tolerance, and reduced external BOM count due to integrated digital voltage-loop compensation.
When designing with this controller, observe the IC's 11 V minimum VCC supply requirement and provide adequate bulk capacitance on the VCC pin with a 100 nF ceramic bypass close to the package. The current-sense resistor value must be calculated against the IC's internal 1.0 V cycle-by-cycle over-current threshold; exceeding this trips protection but should not be relied upon as a primary current limit. PCB layout must keep the gate-drive loop area minimal to avoid ringing above the 17 V gate-clamp rating.

Typical Applications
ICE3PCS01GXUMA1 is suitable for 6 applications: ATX PC Power Supply PFC Front-End, Flat-Panel TV Power Supply, Industrial SMPS Module (300 W to 1000 W), E-Bike and Scooter Charger (100 W to 500 W), High-Bay LED Driver (150 W to 500 W), Universal-Mains Adapter and Open-Frame SMPS.
ATX PC Power Supply PFC Front-End
The ICE3PCS01GXUMA1 is well suited as the 100 W to 600 W boost PFC front-end in ATX12V power supplies where IEC 61000-3-2 mandates PF >0.9 above 75 W. Its 85-265 VAC universal input eliminates the need for voltage-doubler circuitry, and the 21-100 kHz adjustable switching frequency allows the designer to optimize the boost inductor for either 80 Plus Bronze efficiency targets or compact SFX form factors. Placed between the bridge rectifier and the 400 V bulk capacitor, the IC drives the boost MOSFET with a 1.5 A source / 2 A sink totem-pole driver, while integrated digital voltage-loop compensation removes the RC components that legacy designs required. Trade-off: CCM operation at 100 kHz yields roughly 1.5% to 2% higher efficiency than CRM at this power level but requires a larger boost inductor and a current-sense resistor sized for the 1.0 V internal OCP threshold.
Recommended
Flat-Panel TV Power Supply
In 100 W to 300 W LCD/LED TV power supplies the ICE3PCS01GXUMA1 provides the PFC pre-regulator stage that meets ENERGY STAR v8 standby and active-power efficiency requirements. The IC's 1.4 mA quiescent current and integrated soft-start limit inrush current on the 400 V bulk capacitor, allowing smaller NTC thermistor sizing or elimination. The cascaded average-current control maintains low total harmonic distortion (THD <8%) across the universal mains range, which is critical for meeting European Ecodesign Directive 2019/1782. A practical implementation places a 220 uH boost inductor and a 1 uF X2 film sense capacitor on the current-sense path, with the controller frequency set to 65 kHz to balance magnetics size and switching loss in the 200 W TV platform.
Recommended
Industrial SMPS Module (300 W to 1000 W)
For 300 W to 1000 W industrial SMPS modules the ICE3PCS01GXUMA1 serves as the CCM PFC controller in three-phase-input-derived 24 V/48 V DC bus converter front ends. Its -40 C to +125 C operating junction temperature range and integrated digital voltage-loop compensation support the long-life, fan-cooled deployment profile typical of industrial automation racks. Designers pair it with a 600 V or 650 V SiC MOSFET in the boost position to push switching frequency toward the 100 kHz maximum and shrink the boost inductor by 40% relative to 65 kHz designs. Performance trade-off: CCM at high power eliminates the audible valley-switching noise present in CRM designs and supports easier EMI filter design above 150 kHz conducted emissions limits.
Recommended
E-Bike and Scooter Charger (100 W to 500 W)
Battery chargers for e-bikes and electric scooters in the 100 W to 500 W range commonly use the ICE3PCS01GXUMA1 as the universal-input PFC front-end feeding a downstream LLC or QR flyback charger stage. Its 85-265 VAC input covers both 110 V regions (US/Japan) and 230 V regions (EU/China) without hardware switching, enabling a single SKU for global e-mobility products. The 1.0 V cycle-by-cycle over-current protection and integrated soft-start prevent inrush damage to the bulk capacitor when the charger is plugged into a depleted 36 V or 48 V battery pack. A typical 250 W design runs at 80 kHz switching frequency with a 250 uH boost inductor to keep peak inductor current below 5 A at 90 VAC low-line operation.
Recommended
High-Bay LED Driver (150 W to 500 W)
High-bay LED drivers in the 150 W to 500 W class for warehouse and industrial lighting leverage the ICE3PCS01GXUMA1 to achieve PF >0.95 and THD <10% required by DLC Premium and EU 1194/2012 regulations. The integrated digital voltage-loop compensation stabilizes the loop across the wide 0.5 A to 4 A LED load range characteristic of dimmable high-bay luminaires, eliminating the loop-tuning step required by external-compensation PFC ICs. The 1.4 mA quiescent current supports DLC standby power requirements below 0.5 W. In a typical 300 W implementation the IC switches at 70 kHz into a 600 V CoolMOS boost stage, achieving 95% PFC stage efficiency at 230 VAC full load.
Recommended
Universal-Mains Adapter and Open-Frame SMPS
Open-frame SMPS and universal-mains adapters above 100 W use the ICE3PCS01GXUMA1 to provide the active PFC front-end required by IEC 61000-3-2 in Class A and Class D equipment. The IC's wide 11 V to 25 V VCC range allows simple bootstrap supply from the auxiliary winding of the downstream flyback transformer, eliminating a separate PFC auxiliary supply rail. The 14-pin PG-DSO-14 package with industry-standard pinout supports retrofits into legacy ICE2PCS0x designs, where the designer replaces the 2nd-gen controller with the 3rd-gen part to gain digital compensation and reduce BOM by 6 to 8 passive components. Performance trade-off: switching above 80 kHz requires a gate resistor to damp ringing that legacy designs may not have needed.

Design Notes
Keep the gate-drive loop from the IC's GATE pin through the external gate resistor to the boost MOSFET gate and back to the IC's GND pin as small as possible (target loop area below 50 mm^2). Place the current-sense resistor (typically 20 to 50 milliohm) directly at the IC's GND pin return path with the ISENSE pin trace routed as a Kelvin connection. Place the 100 nF VCC decoupling ceramic capacitor within 2 mm of the VCC pin, and bulk-decouple the VCC rail with at least 10 uF of additional capacitance to handle the gate-charge current spikes without VCC droop below the 11 V UVLO threshold.
Estimated thermal analysis: at 80 kHz switching frequency driving a 600 V CoolMOS with 30 nC Qg, the IC's gate-driver dissipation is approximately P_gate = Qg * Vgate * fsw = 30 nC * 12 V * 80 kHz = 29 mW, which is negligible. However, in designs where the IC's VCC is supplied from an auxiliary winding rather than a dedicated regulator, the supply-current drawn from VCC at light load can push the package dissipation above 500 mW; provide at least 100 mm^2 of copper pour on the PG-DSO-14 thermal pad area to keep junction temperature rise below 30 C at +85 C ambient.
Do not connect a switching converter's gate directly to the IC's GATE pin without a series gate resistor (typically 10 to 33 ohm). The ICE3PCS01GXUMA1's 17 V gate-clamp rating can be exceeded by ringing on long gate traces, causing premature MOSFET failure. Also note that the IC's VCC must rise above the 11 V UVLO turn-on threshold before the gate driver is enabled; designs that rely on VCC supplied from the boost output before PFC regulation has stabilized can experience start-up oscillation. Provide a 1 mA to 5 mA startup resistor from the rectified mains to VCC with adequate debounce.
