Murata has announced the expansion of the PAH series "half-brick" DC-DC power converters from Murata Power Solutions: the PAH-28/12.5-D24 model.

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, wireless networks, and telecom applications. The baseplate provides a means for conduction cooling in demanding thermal environment conditions.

The module provides a 28Vdc output at 12.5 Amps and accepts a wide input voltage range of 18-36 Vdc. The PAH topology offers high efficiency (up to 92.5%), tight line and load regulation, low ripple/noise, and a fast dynamic load response. A single-board, highly optimized thermal design contributes to superior thermal performance.
