Product Overview

The TPS54020RUWT is a step-down SWIFT™ Converter with out-of-phase synchronization. The TPS54020 operates at continuous current mode (CCM) at higher load conditions and transitions to eco-mode while skipping pulses to boost the efficiency at light loads. Current limiting on both MOSFETs provides device and system protection. Cycle-by-cycle current limiting in the high-side MOSFET protects for overload situations. Low-side MOSFET zero current detection turns off the low-side MOSFET while operating under light loads. Three selectable current-limit thresholds allow a good fit for various applications. A hiccup or cycle-by-cycle overcurrent protection scheme is also selectable. Thermal shutdown protection disables switching when die temperature exceeds the thermal shutdown trip point and enables switching after the built-in thermal hysteresis and shutdown hiccup time. The SS pin controls the output voltage start-up ramp and allows for selectable soft-start times.
  • Integrated 8 and 6mΩ MOSFETs
  • Peak current-mode control
  • Eco-mode™ pulse skip for higher efficiency
  • Overcurrent protection for both MOSFETs
  • Synchronizes to external clock
  • Start-up into pre-biased outputs
  • Over-temperature and overvoltage protection
  • Adjustable soft-start and power sequencing
  • Power-good output monitor for undervoltage and overvoltage
  • SYNC_OUT function provides output clock signal 180° out-of-phase
  • 0.6V Voltage reference with ±1% accuracy
