ISL8282M

DATASHEET ISL8282M 15A High Efficiency Hybrid Digital Step-Down Power Module FN9365 Rev.1.00 Feb 14, 2019 The ISL8282M is a PMBus enabled DC/DC single channel step-down power supply featuring the proprietary Renesas R4™ Technology. The module supports a wide 4.5V to 16.5V input voltage range and a wide 0.5V to 5V output range capable of delivering up to 15A of continuous current. The ISL8282M achieves up to 95% conversion efficiency and is optimized for high power density. Integrated LDOs provide module bias voltage allowing for single supply operation. The ISL8282M includes a SMBus/PMBus/I2C interface for device configuration, telemetry (VIN, VOUT, IOUT, and temperature), and fault reporting. The proprietary Renesas R4 control scheme has extremely fast transient performance, accurately regulated frequency control, and all internal compensation. An efficiency enhancing PFM mode greatly improves light-load efficiency. The ISL8282M’s serial bus allows for easy R4 loop optimization...
