ISL6744A
Intermediate Bus PWM Controller
The ISL6744A 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 as low as 35ns, and overcurrent shutdown. The ISL6744A is identical to the ISL6744, but is optimized for higher noise environments.
Low start-up and operating currents allow for easy biasing in both AC/DC and DC/DC applications.
