Introduction

AI Translation

The TPS54202H is a 2A synchronous buck converter with an input voltage range of 4.5V to 28V. The device integrates two switching FETs and features internal loop compensation and a 5ms internal soft-start, reducing component count. By integrating MOSFETs in a SOT-23 package, the TPS54202H achieves high power density with a minimal PCB footprint. Advanced Eco-mode operation maximizes light-load efficiency and reduces power dissipation. Cycle-by-cycle current limiting on the high-side MOSFET protects the converter under overload conditions, with enhanced protection provided by a low-side MOSFET freewheeling current limit that prevents current runaway. When the overcurrent duration exceeds a preset time, hiccup-mode protection is triggered.
