TPS62821 - Step-Down Converter

Description

The TPS6282x is an all-purpose and easy to use synchronous step-down DC-DC converter with a very low quiescent current of only 4 µA.

It supplies up to 3A output current (TPS62823) from a 2.4-V to 5.5-V input voltage.

Based on the DCS-Control™ topology it provides a fast transient response.

Features

  • 1 DCS-Control™ topology.
  • 26-mΩ/25-mΩ internal power switches (TPS62823).
  • Up to 3-A output current (TPS62823).
  • Very low quiescent current of 4 µA.
  • Switching frequency of typically 2.2 MHz.
  • 1% feedback voltage accuracy (full temp. range).
  • Enable (EN) and power good (PG).
  • Adjustable output voltage from 0.6 V to 4 V.
  • 100% duty-cycle mode.
  • Internal soft-start circuitry.
  • Seamless power save mode transiti.
