Overview The ISL8212MEVAL1Z evaluation board (shown in Figures 4 and 5) is designed for evaluating the ISL8212M. The ISL8212M is a single channel, synchronous step-down DC/DC power supply module that is capable of delivering up to 15A of continuous current. The proprietary Renesas R4 Technology control 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 ISL8212MEVAL1Z evaluation board is a 3 x 3 inch six-layer FR4 board with 2oz. copper on all layers. The ISL8212MEVAL1Z operates from a single 4.5V to 15V wide input power rail and offers adjustable output voltages down to 0.5V and efficiencies of up to 95%. The ISL8212MEVAL1Z comes with placeholders for pin-strap resistors to set up output voltage, PFM/PWM mode, temperature compensation (TCOMP), switching frequency (f ), AV gain, SW OCP retry/latch-off, ultrasonic PFM enable, soft-start ramp rate, RR impedance, and AV gain multiplier (1x or 2x). By default, the ISL8212MEVAL1Z is set to a 1V output voltage with a 400kHz switching frequency, 49 AV gain, and 200k RR. 1.1 Key Features Input voltage range: 4.5V to 15V, capable of delivering up to 15A of continuous current and up to 95% conversion efficiency Adjustable output voltage: 0.5V to 5V with 1.5% load/line/temperature regulation with remote sense Proprietary Renesas R4 Technology Programmable V , PFM/PWM mode, TCOMP, f , AV gain, OCP retry/latchoff, ultrasonic PFM enable, OUT SW soft-start ramp rate, RR, and AV gain multiplier Startup into precharged load Dedicated enable pin and PGOOD indicator Comprehensive fault protection for high system reliability: over-temperature protection, output overcurrent and short-circuit protection, output overvoltage and undervoltage protection, open remote sense protection, input UVLO and power sequence, and fault reset Thermally enhanced 12mmx11mmx5.3mm HDA package 1.2 Specifications The ISL8212MEVAL1Z is configured and optimized for the following operating conditions: V = 4.5V to 15V IN V = 1V OUT I = 15A OUT-MAX f = 400kHz SW AV gain multiplier = 2x, AV gain = 49, RR = 200k TCOMP = +5C R12UZ0037EU0101 Rev.1.02 Page 2 of 36 Feb 15, 2019
