ISL6721 Flexible Single-Ended Current Mode PWM Controller

DATASHEET ISL6721 Flexible Single-Ended Current Mode PWM Controller FN9110 Rev 9.00 May 20, 2016 The ISL6721 is a low power, single-ended Pulse Width Modulating (PWM) current mode controller designed for a wide range of DC/DC conversion applications including Boost, Flyback and isolated output configurations. Peak current mode control effectively handles .

Features

include a low power mode where the supply current drops to less than 200µA during overvoltage and overcurrent shutdown faults. This advanced BiCMOS design features low operating current, adjustable operating frequency up to 1MHz, adjustable soft-start, and a bidirectional SYNC signal that allows the oscillator to be locked to an external clock for noise sensitive applications. Applications
• Telecom and datacom power
• Wireless base station power
• File server power
• Industrial power systems
• Isolated buck and Flyback regulators
• Boost regu.
