4:1 Input, 120W Output

8th Brick DC-DC Converters

with improved efficiency & thermal performance

Londonderry, NH – March 28, 2025 – Semiconductor Circuits, Inc. expands and improves it’s line of 4:1 input (9-36, 18-72) Cool Power Technologies 8th brick DC-DC converters designed for use in industrial, solar, test, telecom/communications, POE, networking, data-processing, railway, military, medical and aerospace applications. This updated line of high efficiency (92% typical) 120W output modules has significantly improved thermal performance & can directly replace larger quarter brick modules saving space and cost (identical pin out and functionality.) These converters feature an industry standard 9-36Vdc or 18-72Vdc (12, 24 or 48Vdc nominal) input voltage ranges and come in 3.3V@36A, 5V@24V and 12V@10A versions. The modules are available as an open frame design or with an optional baseplate for those applications where conduction cooling is required or preferred. This module is compliant with DOSA footprint and interface standards. Please visit www.dcdc.com for technical datasheets & to order samples.

These modules meet UL 62638-1, EN/IEC 62638-1+A11, CSA C22.2 No. 62638-1 requirements and are UL94 V-0 flammability rated. The modules meet or exceed the typical industry requirements including no load/no minimum capacitance operation and 2X nominal input voltage transient capability.

Other features include: fixed-frequency operation, auto-restart OVP, OCP & OTP protections, UVLO and remote sense. Remote ON/OFF is standard with positive or negative logic options available.

Sample quantities can be ordered directly from stock via the website or through Digikey. Please contact sales@dcdc.com or call 603-893-2330 for OEM pricing and availability. Other output voltages (e.g. 24V, 30V & 48V) are available in the 4:1 input series  – visit www.dcdc.com for more information. We also welcome quick-turn modifications and custom configurations to meet our customer’s particular requirements.
