Low-Cost Single-Ended Current-Mode
PWM for Microcontroller Based Power
Converters
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.
