TEXAS INSTRUMENTS TPS54020RUWT 直流-直流开关降压逐步递减稳压器, 可调, 4.5V-17V输入, 600mV-5V输出, 10A输出, VQFN-15
The 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.
