The PH series provides up to 310W/50A outputs with industry standard half brick package. The efficient Non-SR technology combining with ultra low leakage inductance magnetic gives converters ”SR-like” conversion efficiency and high reliability, the single component side board designed with Sink-Plate technology
eliminate the hot spot gives converter better thermal performance. Modules are designed for Telecom, Servers, Networking equipments and other applications that use a 24V or 48V (36~75V) input bus.

Options for PH Series are listed as follows:
A (Enable Logic): P: Positive N: Negative
B (Pin Dimension): 0: 0.12” 1: 0.16” 2: 0.20” 3: 0.24”
C (Standoff Height): 0: 0.02” 1: 0.08” 2: 0.16”
D (Base-Plate/Module Thickness): M: 1.0mm Metal Plate/0.34” A: 3.0mm Sink-Plate/0.42” B: 5.0mm Sink-Plate/0.50”
E: 1.0mm Metal Plate with Metal Enclosure/0.34”
E F (Output): 00 to 99 for output current rating
Example: PH48120N00E-21 is a PH series half brick 48V to 12V/21A dc/dc converter with negative control logic, 0.12” pin length, 0.02” of
standoff height and 1.0mm Metal Plate with Metal Enclosure. The total height of this module is 0.02”+0.34”=0.36”
