ISL8117 - Synchronous Step-Down PWM Controllers
ISL8215M Not Recommended for New Designs

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. The ISL8215M is based on a valley current mode PWM control scheme and 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. A 40ns typical minimum on-time and an adjustable operating frequency allow it to support low duty cycle, single-step down conversions to point-of-load voltages and its operating frequency can also be synchronized with an external clock signal. The ISL8215M implements a selectable Pulse Skipping Mode (PSM) with Diode Emulation Mode (DEM) to improve light-load efficiency for battery related applications. A programmable soft-start reduces the inrush current from the input supply while a dedicated enable pin and power-good flag allow for easy system power rails sequencing with voltage tracking capability. Excellent efficiency and low thermal resistance permit full power operation without heatsinks. Input Undervoltage Lockout (UVLO), over-temperature, programmable overcurrent, output overvoltage, and output prebias start-up protections ensure safe operations under abnormal operating conditions. The ISL8215M is available in a compact RoHS compliant thermally-enhanced 19mm x 13mm x 5. 3mm HDA package.
