The ISL6729 pulse width modulating (PWM) current mode controller is designed for power conversion applications that are based on a microcontroller, or other device, which can generate a digital clock signal at the desired switching frequency. Similar to the ISL684x family of products, the ISL6729 provides the basic current mode PWM control features, but eliminates the error amplifier, the oscillator, and the reference. An external clock signal applied to the oscillator input provides the time base and sets the maximum duty cycle. The reduced feature set is ideal for those applications where a microcontroller is available to provide the monitor and control functions. The analog PWM provides the cycle-by-cycle peak-current mode control, leaving the monitor and control overhead to the microcontroller.
