UCC2541 HIGH-EFFICIENCY SSYNCHRONOUS BUCK PWM CONTROLLER

DESCRIPTION
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 θJC to accommodate the dual high-current drivers on board.

FEATURES
● On-Chip Predictive Gate Drive for
   High-Efficiency Synchronous Buck
   Operation
● Dual ±3-A TrueDrive Outputs
● On-Board Programmable Oscillator with
   1-MHz Frequency Operation
● TR Input for Sequencing Operation
● Overcurrent Protection using a Parallel
   Average Current Mode Control Loop
● 3 Modes to Support 2.7-V to 35-V Input Bias
● Reverse Current Protection for Output Stage
● User Programmable Shutdown Using SS Pin
● ±1.0% Initial Tolerance Bandgap Reference
● High Bandwidth Error Amplifiers
● Thermally Enhanced HTSSOP 20-Pin
   PowerPAD Package and QFN−32 Pin
● Synchronization Input
● Supports Pre-Bias Applications

APPLICATIONS
● High Efficiency Non-Isolated Converters
   Requiring Advanced Features such as
   Pre-Bias Support and Tracking Capability
● Point-of-Load Modules for Servers, Telecom,
   and Data communication Equipments
● Good for Input Voltages of 3.3 V, 5.0 V,
   12.0 V, or Intermediate Bus Voltages
