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.
The ISL6729 is a low‑cost, single‑ended current‑mode PWM controller intended for microcontroller‑based power converters. It requires an external clock signal for timing and provides a 5 V operation, 1 A MOSFET gate driver, and fast transient response.
The device operates from –40 °C to 105 °C, supports supply voltages of 4.75 V–5.25 V, and can handle clock frequencies up to 2 MHz with a maximum duty cycle of 99 %. It is offered in SOIC and MSOP packages and is Pb‑free compliant.
