The CTH series is designed for high temperature high slew rate step load applications using a 24V or 48V (36~75V) input bus to provide two isolated converters with up to 250 watts power or 25A+25A current with industry standard compatible pin assignments. It provides the best flexibility to reduce the complexity of the system design.

Options for CTH Series are as follows:
V1 (Output voltage): A5, A2, 50, 33, 25, 18 and 15 for 15V, 12V, 5.0V, 3.3V, 2.5V, 1.8V and 1.5V
V2 (Output voltage): A5, A2, 50, 33, 25, 18 and 15 for 15V, 12V, 5.0V, 3.3V, 2.5V, 1.8V and 1.5V
A (Enable Logic): P: Positive N: Negative
B (Pin Length): 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”
EF (V1 current): “00~99 for Output Current Rating
GH (V2 current): “00~99 for Output Current Rating
Example: CTH485033N20A-2525 is a 48V to 5.0V25A / 3.3V25A dual output dc/dc converter with negative control logic 0.20” pin
length, 0.02” standoff height and 3.0mm Sink-Plate. The total height of this module is 0.02”+0.42”=0.44”
