Key Differentiators
- Integrated inductor reduces solution size (vs Discrete buck converters)
- Wide input voltage range (3V to 17V) (vs LTM4624 (4V to 14V))
- High switching frequency (2.2MHz) (vs LTM4624 (1MHz))
Design Notes
Place the TPS82130SILR close to the load to minimize parasitic inductance and resistance. Use a solid ground plane and connect the thermal pad to a large copper area for heat dissipation. Ensure input and output capacitors are placed as close as possible to the module pins, with short, wide traces to reduce ESL and ESR.
At high output currents, the TPS82130SILR dissipates significant power. For example, at 12V input, 3.3V output, and 3A load, power dissipation is approximately 26W (assuming 90% efficiency). The uSIP package has limited thermal capability, so a large copper pour and thermal vias are essential. Consider derating output current at high ambient temperatures.
Do not exceed the absolute maximum input voltage of 17V. Ensure the feedback resistors are 1% tolerance or better to maintain output voltage accuracy. The enable pin should not be left floating; tie it to VIN if not used. Use a 10uF input capacitor and a 22uF output capacitor as recommended in the datasheet for stable operation.
