TPS54308 Datasheet Synchronous 350-khz Fccm Step-down Converter

Manufacturer: Texas Instruments

Overview: www.ti.com SLUSCV2A – JUNE 2017 – REVISEDTTAPPPSSR55IL442330002881 SLUSCV2A – JUNE 2017 – REVISED APRIL 2021 TPS54308 4.

General Description

The TPS54308 is a 4.5-V to 28-V input voltage range, 3-A synchronous buck converter.

The device includes two integrated switching FETs, internal loop compensation, and 5-ms internal soft start to reduce component count.

By integrating the MOSFETs and employing the SOT-23 package, the TPS54308 achieves high power density and offers a small footprint on the PCB.

Key Features

  • 4.5-V to 28-V wide input voltage range.
  • Integrated 85-mΩ and 40-mΩ MOSFETs for 3-A, continuous output current.
  • Low 2-μA shutdown, 300-μA quiescent current.
  • Internal 5-mS soft start.
  • Fixed 350-kHz switching frequency.
  • Peak current mode control.
  • Internal loop compensation.
  • Overcurrent protection for both MOSFETs with hiccup mode protection.
  • Overvoltage protection.
  • Thermal shutdown.
  • SOT-23 (6) packag.
