The COQ series provides up to 180W/50A outputs with industry standard quarter brick package. The efficient SR stage combining with patented “Buck Reset” topology reduce power loss to achieve 145W/in3 power density, 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 COQ 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 F (Output): 00 to 99 for output current rating
Example: COQ48033N00A-35 is a COQ series quarter brick 48V to 3.3V/35A dc/dc converter with negative control logic, 0.12” pin length,

0.02” of standoff height and 3.0mm Sink-Plate. The total height of this module is 0.02”+0.42”=0.44”
