Aug 30, 2017 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. 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 …
