TPS55340 Datasheet Boost/sepic/flyback DC/dc Regulator

Manufacturer: Texas Instruments

Overview: TPS55340 SLVSBD4E – MAY 2012 – REVISED SEPTEMBER 2021 TPS55340 Integrated 5-A Wide Input Range Boost/SEPIC/Flyback DC/DC Regulator.

General Description

The TPS55340 is a monolithic, nonsynchronous, switching regulator with integrated 5-A, 40-V power switch.

The device can be configured in several standard switching-regulator topologies, including boost, SEPIC, and isolated flyback.

The device has a wide input voltage range to support applications with input voltage from multicell batteries or regulated 3.3-V, 5-V, 12-V, and 24-V power rails.

Key Features

  • Internal 5-A, 40-V low-side MOSFET switch.
  • 2.9-V to 32-V input voltage range.
  • ±0.7% reference voltage.
  • 0.5-mA operating quiescent current.
  • 2.7-µA shutdown supply current.
  • Fixed frequency current mode PWM control.
  • Frequency adjustable from 100 kHz to 1.2 MHz.
  • Synchronization capability to external clock.
  • Adjustable soft-start time.
  • Pulse skipping for higher efficiency at light loads.
  • Cycle-by-cycle.
