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.
