Application-specific EZBuck regulator powers Intel Rocket Lake Platform CPUs

Two application-specific EZBuck regulators have been designed by Alpha and Omega Semiconductor to support VCCIO rails in Intel’s Rocket Lake platforms.

The AOZ2263VQI-01 and AOZ2263VQI-02 EZBuck regulators have adjustable output voltage and are claimed to offer the industry’s most compact footprint.

The AOZ2263VQI-01 and AOZ2263VQI-02 are offered in a QFN 4.0 x 4.0mm package. Intel’s Rocket Lake platform consists of two VCCIO rails, the VCCIO_0 and VCCIO_1_2 power multiple I/O. High-performance, personal computing systems support add-on features which require high speed I/O communication, points out Alpha and Omega Semiconductor (AOS). These feature-rich PC systems require VCCIO rails with high currents and typical competing power implementations require either a controller with external discrete power FETs or a converter with a large package. AOS says its integrated devices include all the power silicon in a single QFN package for 12A.

The 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 1.05, 1.075, 1.1, 1.125, and 0.8, 0.95, 1.0, 1.05V, respectively, depending on multiple systems operating modes. Both devices have passed all the validation requirements included in the Intel Rocket Lake platform component list. This validation puts the regulator through stringent tests to ensure compliance with Intel specifications.

AOS’s proprietary COT architecture provides fast load transient response performance and enables stable and low voltage ripple operation with small-sized ceramic capacitors, to further reduce size and cost, says the company.

The AOS EZBuck family is characterised by its level of integration. Devices feature a PGOOD output, an integrated bootstrap diode and integrated soft start. Protection features include cycle-by-cycle current limit, short-circuit protection, over-voltage protection and thermal shutdown. A low power mode pin also allows system designers to lower VCCIO rails down to 0V to minimise system power consumption in standby or idle modes.

The AOZ2263VQI-01 and the AOZ2263VQI-02 are immediately available in production quantities with a lead-time of 12 weeks.
