Product Specification
| Description | PowerVFQFN-31 Power Driver Modules RoHS | Mfr. Part # | AOZ5039QI |
| Package | PowerVFQFN-31 | Model Number | AOZ5039QI |
The AOZ5039QI is a high-efficiency synchronous buck power stage module designed for demanding applications. It integrates two asymmetrical MOSFETs and a driver, with each MOSFET optimized for its role in the synchronous buck configuration. The high-side MOSFET is engineered for fast switching at low duty cycles, while the low-side MOSFET offers ultra-low ON resistance to minimize conduction losses. Housed in a compact 5mm x 5mm QFN package, it minimizes parasitic inductance for reduced EMI. The AOZ5039QI supports TTL and Tri-state compatibility via PWM and FCCM inputs, offering features like an integrated bootstrap diode, diode emulation mode for asynchronous operation, and an optimized pin-out for low-inductance routing. It is suitable for use in servers, notebook computers, VRMs for motherboards, point-of-load DC/DC converters, memory and graphic cards, and video gaming consoles.
