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.
33.0 × 13.5 × 4.2 mm
Applications:
• Communication devices
• Computer server
• Other low power conversion
