Product Summary

The TPS40100RGET is a mid voltage, wide-input (between 4.5 V and 18 V), synchronous, step-down controller. The TPS40100RGET offers programmable closed loop soft-start, programmable UVLO (with programmable hysteresis), programmable inductor sensed current limit and can be synchronized to other timebases. The TPS40100 incorporates MOSFET gate drivers for external N-channel high-side and synchronous rectifier (SR) MOSFET. The applications of the TPS40100RGET include Servers, Networking Equipment, Cable Modems and Routers, XDSL Modems and Routers, Set-Top Boxes, Telecommunications Equipment, Power Supply Modules.
