Low Noise Quasi-Resonant Control DC/DC converter IC for AC/DC Converter

Overview

TopologyLLC Resonant Converter
Input voltage300-900 V
Switching frequency106-134 kHz
Output 125.2 V / 1 A
IC revision001

Description

The BD7682FJ-EVK-401, BD7682FJ-EVK-001 evaluation board outputs 24 V voltage from the input of 300 Vdc to 900 Vdc. The output current supplies up to 1 A. The BD768xFJ-LB series are Quasi-Resonant switching AC/DC converter for driving SiC (Silicon Carbide)–MOSFET. Using external switching MOSFET and current detection resistors provides a lot of flexibility in the design. Power efficiency is improved by the burst function and the reduction of switching frequency under light load conditions. This is the product that guarantees long time support in the Industrial market.

Features

  • Quasi-resonant method(Maximum frequency control 120kHz)/Current mode
