BR202

BR202/203 POL Converter Module for 12 V System Intermediate Bus Features and Benefits Industry standard footprint Improved soldering: gold-plated pads and side notches Synchronized rectifying type stepdown chopper High power High efficiency: ▫ BR202, 88.5% at VIN = 12 V, VO = 1.2 V, IO = 11 A ▫ BR203, 93.4% at VIN = 12 V, VO = 3.3 V, IO = 12 A Operating temperature range: –40°C to 85°C Input voltage range: 10.8 to 13.2 VDC Output voltage: BR202, 0.75 to 1.65 V; BR203, 1.6 to 3.63 V Output current range: 0 to 20 A Operating frequency: BR202, 300 kHz; BR203, 400 kHz Overcurrent protection function Package: Module Description The BR202 and BR203 are thin type POL converter modules with an industry standard exterior shape and footprint, responsive to very high speed loads and compatible with ceramic capacitors. They can be used as design-free POL converters for a 12 V system intermediate bus. They can be configured easily, reducing overall design time, and allowing reuse of designs. Miniaturization was achieved by high frequency switching technology, allowing saving space on the application PCB. Soldering capability has been significantly improved by adoption of end face through holes.
