TPS54308 4.5V to 28V Input, 3A Output, 350kHz Synchronous FCCM Buck Converter in SOT23 Package Datasheet

describe

The TPS54308 is a 3A synchronous buck converter with an input voltage range of 4.5V to 28V. The device contains two integrated switching field effect transistors (FETs) and features internal loop compensation and 5ms internal soft-start to reduce component count.

By integrating MOSFETs in a SOT-23 package, the TPS54308 achieves high power density with a very small footprint on the printed circuit board (PCB).

Under light load conditions, the TPS54308 operates in forced continuous conduction mode (FCCM), maintaining a nearly constant switching frequency over the entire load range.

Cycle-by-cycle current limit on the high-side MOSFET protects the converter during overload conditions and is enhanced by the low-side MOSFET freewheeling current limit to prevent current runaway. When the overcurrent duration exceeds the preset time, the hiccup mode protection function will be triggered.
