ISL6744A規(guī)格書詳情
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.
Features
? Precision Duty Cycle and Deadtime Control
? 100μA Start-up Current
? Adjustable Delayed Overcurrent Shutdown and Restart
? Adjustable Oscillator Frequency Up to 2MHz
? 1A MOSFET Gate Drivers
? Adjustable Soft-Start
? Internal Over Temperature Protection
? 35ns Control to Output Propagation Delay
? Small Size and Minimal External Component Count
? Input Undervoltage Protection
? Pb-Free (RoHS Compliant)
Applications
? Telecom and Datacom Isolated Power
? DC Transformers
? Bus Converters
