AOS: application-specific EZBuck regulator for Intel Rocket Lake platform

Posted 20 April 2021

Alpha and Omega Semiconductor (AOS) introduced a new family of application-specific EZBuck regulators. AOZ2263VQI-01 and AOZ2263VQI-02 converters include features specifically designed to meet the Intel Rocket Lake Platform’s specifications. The 2-bit VID pins allow the VCCIO_0 and VCCIO_1_2 power rail to adjust with voltage for 1.05V, 1.075V, 1.1V, 1.125V, and 0.8V, 0.95, 1.0V, 1.05V, respectively, depending on multiple systems operating modes.

Both devices have also passed all the validation requirements included in the Intel Rocket Lake Platform component list.

AOS’s proprietary COT architecture provides ultra-fast load transient response performance and enables stable and low voltage ripple operation with small-sized ceramic capacitors, further reducing solution size and cost.

Protection features include cycle-by-cycle current limit, short-circuit protection (SCP), Overvoltage Protection (OVP) and Thermal shutdown. A Low Power Mode (LPM) pin also allows system designs to lower VCCIO rails down to 0V for minimizing system power consumption in standby or idle mode.
