Intersil — ISL8215M: 15A 42V Single-Channel DC/DC Step-Down Power Module

The ISL8215M power module is a single-channel, synchronous step-down, non-isolated complete power supply, capable of delivering up to 15A of continuous current. Operating from a single 7V to 42V wide input power rail and integrating the controller, power inductor, and MOSFETs, the ISL8215M requires only a few external components to operate and is optimized for space constrained applications. Based on a valley current mode PWM control scheme, the ISL8215M provides fast transient response and excellent loop stability. It offers an adjustable output voltage range of 0.6V to 12V with better than 1.5% accuracy over line, load, and temperature.
