Configurable, 6-Phase, 3 Output Client Computing PMIC for IMVP9.2 Applications

The RAA225019 is a highly configurable PMIC for Intel IMVP9.2 Lunar Lake applications. It features fully integrated power MOSFETs, controllers, and current-sensing circuitry, and adopts high switching frequency for high power-density and efficiency for small form factor design.

Six phases can be distributed across three outputs (two SVID rails and one auxiliary rail). The SVID1 rail operates from a max phase count of 2 to 6 while the SVID2 and BUCK3 rails can run either a 1-phase or 2-phase configuration. Additionally, the device contains an integrated LDO with a Power Gate bypass option.

The PMIC uses the Renesas Robust Ripple Regulator technology with its many advantages as compared to traditional modulation schemes. Output capacitance requirements are minimized because of fast transient settling time and a variable switching frequency in response to load transients. Light load efficiency is boosted through APM and auto-DCM with natural period stretching at low load currents, benefiting standby battery life.
