The Renesas Electronics voltage controllers is a low cost, primary side, double-ended controller intended for applications using full and half-bridge topologies for unregulated DC/DC converters. It is a voltage-mode PWM controller designed for half-bridge and full-bridge power supplies. It provides precise switching frequency control, adjustable soft-start, precise dead time control with dead times, and overcurrent shutdown.

Adjustable oscillator frequency
Internal over-temperature protection
