Texas Instruments TPS54020

Beschreibung

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-downdesigns. The TPS54020 is a full featured converter. High efficiency is achieved through the innovative integration and packaging of the high-side and lowside 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.limiting on both MOSFETs provides device and system protection. Cycle-by-cycle current limitingin the high-side MOSFET protects for overload situations. Low-side MOSFET zero current detection turns off the low-side MOSFET while operating underlight 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 switchingwhen die temperature exceeds the thermal shutdown trip point and enables switching after the built-in thermal hysteresis and shutdown hiccup time.
