The AOZ5166QI-01 is designed for high power density voltage regulators for servers, workstations, graphic cards and desktop PC applications.

The 40pin, 6.0 x 6.0mm QFN package integrates an optimised dual gate driver and two MOSFETs, to produce a high efficiency DC/DC synchronous buck power stage, claims the company.

The company’s proprietary trench MOSFET and packaging technologies contribute to efficiency and thermal performance, reduce switching loss and lower power dissipation for a higher current driving capability. The low RDS (ON) of low-side MOSFET combined with the low Qg high-side MOSFET balances switching and conduction losses to increase overall efficiency by 1%.

The module is available immediately in production quantities. Options are minimum VIN of 4.5V and maximum VIN of 16V (AOZ503QI-01) or 25V for the other four modules in the series. PWM logic is 3.3V (AOZ5036QI-01, AOZ5066QI-01 and AOZ5049QI) or 5.0V (AOZ5066QI and AOZ5049QI).
