ISL8215M

15A 42V Single-Channel DC/DC Step-Down Power Module

Product Status: Mass Production

OVERVIEW

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.

Industry-Leading 10A and 15A Fully Encapsulated PMBus Power Modules

The ISL828xM hybrid digital and ISL821xM analog power modules feature integrated LDOs that enable single-supply operation. They leverage Renesas’ patented R4™ high-speed control loop architecture with inherent line voltage feed-forward, providing designers a unique combination of ultra-fast load transient response and high noise immunity. Their proprietary Grid HDA package offers unmatched electrical and thermal performance through a single-layer conductive package substrate that efficiently transfers heat from the module to the system board, and dissipates it without requiring airflow or heatsinks – even under heavy load conditions.
