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 voltagemode PWM controller designed for half-bridge and fullbridge power supplies. It provides precise control of switching frequency, adjustable soft-start, precise deadtime control with deadtimes as low as 35ns, and overcurrent shutdown. The ISL6744A is identical to the ISL6744, but is optimized for higher noise environments. |
