ISL6721A

DATASHEET ISL6721A Flexible Single-Ended Current Mode PWM Controller FN6797 Rev.1.00 Jul 24, 2018 The ISL6721A 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 power transients and provides inherent overcurrent protection. Other features include a low power mode in which the supply current drops to less than 200µA during overvoltage and overcurrent shutdown faults. The ISL6721A differs from the ISL6721 in that the UVLO and UV thresholds have been modified. 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.
