1EDN7136GXTMA1 Overview
A gate driver IC is a specialized power-management device that sits between a low-power control signal (typically from an MCU or PWM controller) and the gate of a power transistor. It provides the high transient current necessary to charge and discharge the transistor's input capacitance quickly, while providing logic-level translation, isolation, and protection. Within the broader taxonomy, the 1EDN7136 belongs to the hierarchy: gate driver IC → power management IC → semiconductor. As a low-side driver it pulls the gate to a defined reference (ground) and applies VDD with controlled slew rate, critical for GaN devices whose very low Qg demands sharp drive edges.
Key features include a 4 A / 8 A asymmetric source/sink drive capability that overcomes GaN's miller plateau with sub-10 ns transitions, a true low-side topology with non-inverting logic input, integrated under-voltage lockout (UVLO) for both VDD and the GaN gate reference, and TTL-compatible CMOS input thresholds. The PG-VSON-10-4 package offers a low-inductance leadless footprint with a thermal pad, keeping gate-loop parasitics minimal — essential when every nanohenry of source inductance degrades switch-node rise time.
Architecturally, the 1EDN7136 uses a matched totem-pair output stage with separate source and sink paths, allowing the asymmetry that prevents undesired turn-on from miller current while still delivering the high peak current needed at turn-on. Internal gate-voltage regulation adapts the output swing to a GaN-safe level (typically around 6 V), protecting the gate oxide from overstress.
Typical applications include 48 V point-of-load converters, telecom and datacom buck stages, USB-PD adapters, Class-D audio amplifiers, and high-frequency LLC or totem-pole PFC front ends. This part is also used in synchronous rectification stages where the low-side GaN replaces a traditional Si MOSFET for higher efficiency. To retain power integrity, place a 100 nF ceramic decoupling capacitor directly at VDD within 2 mm of the pin, and keep the gate-drive loop area below 5 mm² to suppress ringing.

Typical Applications
1EDN7136GXTMA1 is suitable for 7 applications: 48 V Point-of-Load Buck Converter, Totem-Pole PFC Front End, USB-PD Fast Charger / Adapter, Class-D Audio Amplifier Output Stage, High-Frequency LLC Resonant DC, Synchronous Rectifier in Isolated DC-DC, Solar Micro-Inverter / Optimizer.
48 V Point-of-Load Buck Converter
The 1EDN7136GXTMA1 drives the low-side CoolGaN HEMT in 48 V to 12 V / 5 V point-of-load converters used in telecom, datacom, and AI-server power rails. With 4 A source / 8 A sink capability, it overcomes the miller plateau in under 10 ns, switching the GaN at 1-2 MHz and shrinking magnetics by 40-50% versus Si-MOSFET solutions. The PG-VSON-10-4 package keeps gate-loop inductance below 1 nH, suppressing ringing that would otherwise cost 1-2% efficiency at full load.
Recommended
Totem-Pole PFC Front End
In bridgeless totem-pole PFC stages for 1-3 kW server and EV-chapter supplies, the 1EDN7136GXTMA1 drives the low-side GaN at 100 kHz to 1 MHz. Its sub-nanosecond propagation delay and 8 A sink current absorb the miller-induced reverse current during hard turn-off, eliminating the false turn-on that plagues Si-MOSFET PFC designs. Combined with high-side gate-drive circuitry, the 7136 enables 99% PFC efficiency at 2 kW and reduces heatsink size dramatically.
Recommended
USB-PD Fast Charger / Adapter
The 1EDN7136GXTMA1 powers the synchronous-rectifier GaN stage in 100-240 W USB-PD adapters, replacing Si MOSFETs to reach power densities above 30 W/in³. The 4 A/8 A drive enables 500 kHz to 1 MHz switching in QR or DCM flyback/active-clamp topologies, cutting transformer size by half and easing thermal design for travel adapters. Its GaN-safe gate clamp protects CoolGaN from Vgs overshoot during adapter hot-plug events.
Recommended
Class-D Audio Amplifier Output Stage
The 1EDN7136GXTMA1 drives GaN output stages in 200-1000 W Class-D amplifiers where switching above 1 MHz pushes the loop bandwidth well above the 20 kHz audio band, slashing idle losses by 30-50%. The driver's sub-ns propagation delay preserves audio fidelity by keeping dead-time below 5 ns, reducing THD+N to 0.005%. The PG-VSON-10-4 low-inductance footprint eliminates the gate ringing that would otherwise inject EMI into adjacent analog audio stages.
Recommended
High-Frequency LLC Resonant DC
In 400 V to 48 V LLC resonant converters for hyperscale data centers, the 1EDN7136GXTMA1 drives primary-side GaN switches at 500 kHz to 1 MHz, where ZVS turn-on demands a sharp, repeatable gate edge. The 4 A source current charges the GaN's Qg in roughly 6 ns, while the 8 A sink handles the miller discharge cleanly, keeping circulating current low. This driver enables transformer isolation at 1 MHz, doubling power density versus 200 kHz Si designs.
Recommended
Synchronous Rectifier in Isolated DC-DC
The 1EDN7136GXTMA1 functions as the secondary-side synchronous-rectifier gate driver in 48 V to 12 V isolated bus converters, where CoolGaN replaces Si MOSFETs to push efficiency above 97%. Its 8 A sink current is critical because SR GaNs turn off under hard-commutation conditions, and a weak sink path would leave the device in linear operation for tens of nanoseconds, dissipating significant switching loss.
Recommended
Solar Micro-Inverter / Optimizer
The 1EDN7136GXTMA1 drives the low-side GaN in 600-1500 W solar micro-inverters and DC power optimizers operating at 100-500 kHz. Its -40 C to +125 C operating range and integrated UVLO protect against cold-start undervoltage events common in rooftop installations. Driving CoolGaN at this current level eliminates reverse-recovery losses that limit Si-IGBT designs to 95% efficiency, lifting inverter CEC-weighted efficiency to 98% or higher.

Design Notes
Estimated: with VIN = 48 V, VOUT = 12 V, IOUT = 20 A at 1 MHz switching, power dissipation in the 1EDN7136GXTMA1 itself is dominated by the Qg*Vgs*fSW charge/discharge path. Place a 100 nF X7R 0402 ceramic decoupling capacitor directly at VDD (pin 1) within 2 mm of the lead. Keep the gate-drive loop area below 5 mm² to maintain loop inductance under 1 nH — every additional nanohenry causes visible switch-node ringing above 200 MHz.
At continuous 1 MHz switching into a CoolGaN HEMT with total Qg ~ 3 nC, the driver's gate-drive loss is approximately 18 mW (estimated: P = Qg * Vgs * fSW = 3e-9 * 6 * 1e6). The PG-VSON-10-4 thermal pad tied to GND is sufficient for typical converter duty cycles. Avoid placing the driver more than 5 mm from the GaN gate to prevent high-frequency ringing from coupling into the gate loop.
Use a 4-layer PCB with a continuous ground plane directly under the driver. Route the IN signal on an inner layer or guard it with GND vias on both sides to keep switching noise from coupling back into the controller. The exposed pad (EP) of the PG-VSON-10-4 must be soldered to a continuous copper pour with at least 4 thermal vias (0.3 mm drill, 0.5 mm pitch) for proper heat spreading.
Do not drive Si MOSFETs at high dV/dt with this driver if the application involves long gate leads — the 4 A/8 A drive capability is optimized for low-inductance GaN HEMTs and may cause excessive ringing on Si devices with typical Qg of 30-50 nC. Verify that VDD is above the UVLO threshold before applying IN signals; below UVLO the output stage is in tri-state and the GaN gate floats, which can leave the switch in undefined linear operation.
