Series Description For applications requiring improved electrical and thermal performance, consider Murata's new PAH series "half brick" DC-DC power converters. These compact modules measure 2.3" X 2.4" X 0.5" (58 X 61 X 12.7mm) and offer the industry-standard half brick footprint. The PAH Series is ideal for power amplifier applications, semiconductor test equipment, wireless networks, and telecom applications. The baseplate provides a means for conduction cooling in demanding thermal environment conditions. The module provides a 53Vdc or 48Vdc output at 8.5 Amps and accepts a wide input voltage range of 36-75Vdc. The PAH topology offers high effi ciency (up to 94%), tight line and load regulation, low ripple/ noise, and a fast dynamic load response. A singleboard, highly optimized thermal design contributes to the superior thermal performance. These half-bricks provide output trim, sense pins, and primary side on/off control. Standard features also include input under-voltage shutdown, output over-voltage protection, output short-circuit/ current limiting protection, and thermal shutdown.
