Features

Description

The EPC Space EPCS4001 is a 48 V-input buck converter controller with 12 V nominal (adjustable) output voltage. This converter is developed to provide an efficient solution for DC power conversion and distribution in space applications and High Energy Physics systems. As such, it has been designed for flawless functionality in harsh radiation and magnetic field environments.

The selection of appropriate CMOS technology, coupled to the systematic use of Radiation Hardness by Design (RHBD) techniques, makes the controller capable of continuous operation up to very high radiation limit (50Mrad and 4e14 n/cm2 and 2.23e14 p/cm2(30MeV proton beam). The controller has been designed for operation in a strong magnetic field in excess of 40,000 Gauss and has been optimized for cored and coreless inductors of 200-500nH. To be compatible with these small inductance values, its switching operation is in the 0.5-3MHz range.
