Isolated 1x1 30W 3.3V 9A 4:1 DC-DC Converters

Semiconductor Circuits, Inc. introduces the new ultra-wide input range 3.3V, 9A (30W) 1x1 dc-dc converter. This open frame or optional encapsulated module provides 30W of output power at an output voltage of 3.3Vdc. According to Semiconductor Circuits, it is the only true 30W 3.3V 1x1 4:1 input module available on the market today (5V, 12V, 15V and dual output versions are also available.) This module is suited for industrial or distributed power architecture applications. The module is compliant with the standard 1x2 pinout and interface standards. It has an ultra wide input voltage range of 9- to 36-Vdc (18- to 75-Vdc input versions available) and provides 2250Vdc input to output isolation in open frame configuration, 1600Vdc in the encapsulated module.

The CP30 4:1 input series is ROHS II Directive 2011/65/EU Compliant meets EN 60950 basic insulation requirements and is UL94 V-0 flammability rated. The module complies with all of the typical industry requirements including no load operation, 2X nominal input voltage transient and pre-biased load startup.

Other features include: fixed-frequency operation, auto-restart OVP, OCP & OTP protections, UVLO, remote sense and +/-10% output voltage trim. Remote ON/OFF is standard with positive or negative logic options available. Modules can also be ordered without enable pin, trim pin or without both.

The modules feature a standard 1×2 pinout with dimensions of 0.94” L x 0.94” W x 0.35″ Max. Height (23.9mm x 23.9mm x 8.9mm). The encapsulated versions are standard 1″ x 1″ x 0.4″ Tall (25.4mm x 25.4mm x 10.2mm.)
