PAH-28 Vout, 350-Watt Series www.murata-ps.com Isolated, 350-Watt, Half-Brick DC-DC Converters Output (V) Current (A) Input Voltage (V) 28 12.5 18-36 or 36-75 Typical unit FEATURES PRODUCT OVERVIEW  28Vout @ 12.5A (350W) 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.  Trimmable 16.8 Vout to 32.2 Vout @ 350W with Vin = 18-36V (D24) or 36-75V (D48)  Industry Standard “Half Brick” package  High Efficiency: up to 93%  Outstanding thermal performance  Standard baseplate for conduction cooled applications  No output reverse conduction  Input to Output Isolation, 2250Vdc (Basic) 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.  Input under-voltage lockout The module provides a 28Vdc output at 12.5 Amps and accepts a wide input voltage range of 18-36 or 36-75 Vdc. The PAH topology offers high efficiency (up to 93%), 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.  On/Off Control (Positive or Negative Logic)  Output over-voltage protection  Thermal shutdown  Output short circuit protection (hiccup technique)  Certified to UL 60950-1, CSA-C22.2 No. 60950-1, 2nd edition safety approvals +Vin F1 +Vout Barrier Case ground External DC Power Source NOTE: A minimum of 470µF of capacitance is required on the output to ensure Cout stable operation. An ESR equal to or less than 0.02Ω is also required. Controller and Power On/Off Control Open = On Reference and Error Amplifier logic) -Vin Trim -Vout Figure 1.
