TPS62742 - Step Down Converter

Download the TPS62742 datasheet PDF. This datasheet also covers the TPS62740 variant, as both devices belong to the same step down converter family and are provided as variant models within a single manufacturer datasheet.

Description

The TPS6274x is industry's first step down converter featuring typ.

360nA quiescent current and operating with a tiny 2.2µH inductor and 10µF output capacitor.

This new DCS-Control™ based device extends the light load efficiency range below 10µA load currents.

Features

  • Typ. 360nA Quiescent Current.
  • Up to 90% Efficiency at 10µA Output Current.
  • Up to 300mA / 400mA Output Current (TPS62740/TPS62742).
  • RF Friendly DCS-Control TM.
  • Up to 2 MHz Switching Frequency.
  • Low Output Ripple Voltage.
  • 16 Selectable Output Voltages in 100mV Steps between 1.8V to 3.3V.
  • Automatic Transition to No Ripple 100% Mode.
  • Slew Rate Controlled Load Switch.
