Overview
Description
The ISL8212MEVAL1Z evaluation board is designed to evaluate the ISL8212M single-channel, synchronous step-down DC/DC power supply modules that are capable of delivering up to 15A of continuous current. The proprietary Renesas R4 Technologycontrol scheme has extremely fast transient performance, accurately regulated frequency control, and all internal compensation. The ISL8212M includes four setting up pins (SETx) for module configuration and allows for easy R4 loop optimization that results in fast transient performance across a wide range of applications, including all ceramic output filters. The ISL8212M integrates the controller, all power components, and most passive components. The device requires only a few external components to operate, which significantly reduces design complexity and board space, and it optimizes for high power density applications without the need for airflow or a heatsink.
The ISL821xMEVAL1Z evaluation boards are 3in x 3in 6-layer FR4 boards with 2oz. copper on all layers. The boards operate from a single 4.5V to 15V wide input power rail and offer adjustable output voltages down to 0.5V and efficiencies of up to 95%. They come with placeholders for pin-strap resistors to set up output voltage, PFM/PWM mode, temperature compensation (TCOMP), switching frequency (fSW), AV gain, OCP retry/latch-off, ultrasonic PFM enable, soft-start ramp rate, RR impedance, and AV gain multiplier (1x or 2x).
By default, the ISL821xMEVAL1Z boards are set to a 1V output voltage with a 400kHz switching frequency, 49 AV gain, and 200kΩ RR.
