AOZ6663DI

AOZ6663DI is a power-management IC from Alpha & Omega Semiconductor (AOS). It is a compact, high-efficiency synchronous DC-DC buck regulator with integrated high-side and low-side MOSFETs that converts a higher input voltage to a lower, regulated output.
Key points:
- Integrated FETs for a compact, low‑count design
- Adjustable output with external resistors
- Features such as soft-start, enable/shutdown, and protection (overcurrent/short‑circuit, over‑temperature, UVLO)
- Suitable for core rails and other point‑of‑load applications in portable, embedded, and automotive/industrial systems
- Package and exact specs vary by variant (the DI suffix denotes a specific package/variant and current rating)
For precise input/output ranges, pinout, package type, efficiency, and protection details, consult the official AOZ6663DI datasheet from Alpha & Omega Semiconductor or your distributor.

Pin count: 8 pins.
Function: Dual high-side load switch (two MOSFET power switches) with separate enable controls to switch two loads from VIN; includes current limiting/protection features.

AOZ6663DI is manufactured by Alpha & Omega Semiconductor (AOS). AOS is a fabless semiconductor company that designs and markets power management ICs and power MOSFETs for high-efficiency switching power supplies and related applications.

AOZ6663DI is a dual N-channel power MOSFET used for high-efficiency switching in DC-DC converters. Applications include: synchronous buck/boost regulator stages, load switches and hot-swap circuits, battery-powered devices, automotive ECUs/infotainment, LED driver power stages, and industrial/telecom power supplies and data-center PSUs.

QFN package, typically 16-pin (4x4 mm) with an exposed pad. Please verify with the official datasheet for the exact variant.
