Datasheet
ISL6729 is a low-cost single-ended current-mode PWM controller designed for power conversion applications based on a microcontroller. It provides basic current mode PWM control features, but eliminates the error amplifier, oscillator, and reference. An external clock signal is used as the time base and sets the maximum duty cycle. This product is ideal for applications where a microcontroller is available to provide monitoring and control functions.
User Manual
