The UCC2541 is a synchronous buck PWM controller for high current and low output voltage applications.
For higher efficiency, it incorporates the Predictive Gate Drive™ technology that virtually eliminates body diode conduction losses in synchronous rectifiers.
The UCC2541 is available in the extended temperature range of -40°C to 105°C and is offered in thermally enhanced PowerPAD™ 20-pin HTSSOP (PWP) or 32-pin quad flatpack (RHB) package. This space saving package with standard 20-pin TSSOP footprint has a drastically lower thermal resistance of 1.4°C/W 
JC to accommodate the dual high-current drivers on board.
