Overview: www.ti.com SLVSD26B – APRIL 2016 – REVISEDTTAPPPSSR55IL442220002221 SLVSD26B – APRIL 2016 – REVISED APRIL 2021 TPS54202 4.

General Description

The TPS54202 is a 4.5-V to 28-V input voltage range, 2-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 TPS54202 achieves the high power density and offers a small footprint on the PCB.

Key Features

  • 4.5-V to 28-V wide input voltage range.
  • Integrated 148-mΩ and 78-mΩ MOSFETs for 2-A, continuous output current.
  • Low 2-μA shutdown, 45-μA quiescent current.
  • Internal 5-mS soft start.
  • Fixed 500-kHz switching frequency.
  • Frequency spread spectrum to reduce EMI.
  • Advanced Eco-mode™ pulse skip.
  • Peak current mode control.
  • Internal loop compensation.
  • Overcurrent protection for both MOSFETs with hiccup mode protecti.
