HPC46003V20 IC MCU 16BIT ROMLESS 68PLCC National Semiconductor

Half-brick DC-DC Converter

The InQor® Half-brick converter series is composed of next-generation, board-mountable, isolated, fixed switching frequency dc-dc converters that use synchronous rectification to achieve extremely high power conversion efficiency. Each module is supplied completely encased to provide protection from the harsh environments seen in many industrial and transportation applications.
