The TPS54020 is a 10-A, 4.5-V to 17-V input SWIFT converter. The innovative 3.5-mm × 3.5-mm HotRod package optimizes high-density step-down designs. The TPS54020 is a full-featured converter.

High efficiency is achieved through the innovative integration and packaging of the high-side and low-side MOSFETs. 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.
