ISL62882BHRTZ

Special Purpose Regulators Overview

The ISL62882BHRTZ is a multiphase PWM buck regulator designed for Intel IMVP-6.5™ mobile CPU and GPU core power supplies. It operates with an input voltage range of 4.75V to 5.25V, delivering up to 60A across two output phases. The device utilizes Robust Ripple Regulator (R3) technology for variable switching frequency control, enhancing transient response and light-load efficiency. Key specifications include a 7-bit VID input supporting 0V to 1.500V in 12.5mV steps, lossless inductor DCR current sensing, and differential remote voltage sensing. It is housed in a 40-TQFN package.
