ISL6741 Datasheet

PMIC - Voltage Regulators - DC DC Switching Controllers


The ISL6740, ISL6741 family of adjustable frequency, low power, pulse width modulating (PWM) voltage mode (ISL6740) and current mode (ISL6741) controllers is designed for a wide range of power conversion applications using half-bridge, full bridge, and push-pull configurations. These controllers provide an extremely flexible oscillator that allows precise control of frequency, duty cycle, and deadtime. ISL6741 Features • Precision Duty Cycle and Deadtime Control• 95μA Start-up Current• Adjustable Delayed Overcurrent Shutdown and Re-start (ISL6740)• Adjustable Short Circuit Shutdown and Re-start• Adjustable Oscillator Frequency Up to 2MHz• Bidirectional Synchronization• Inhibit Signal• Internal Over-Temperature Protection• System Over-Temperature Protection Using a Thermistor or Sensor• Adjustable Soft-start• Adjustable Input Undervoltage Lockout• Fault Signal• Tight Tolerance Voltage Reference Over Line, Load, and Temperature• Pb-Free Available (RoHS Compliant) ISL6741 Applications • Telecom and Datacom Power• Wireless Base Station Power• File Server Power• Industrial Power Systems• DC Transformers and Buss Regulators
