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.
Low start-up and operating currents allow for easy biasing in
both AC/DC and DC/DC applications. This advanced
BiCMOS design features low start-up and operating
currents, adjustable switching frequency up to 1MHz, 1A
FET drivers, and very low propagation delays for a fast response to overcurrent faults.
