TPS55340 - Boost/SEPIC/Flyback DC/DC Regulator

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.

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.
