Overview
Description
AO3480 is a power MOSFET (N-channel) from Alpha & Omega Semiconductor. It’s used as a switching transistor in power-management circuits such as DC-DC converters and load switches. The device is enhancement-mode with features like low threshold, low on-resistance, fast switching, and a body diode. It is offered in common SMT packages; exact ratings (Vds, Id, Rds(on)), package size, and thermal specs vary by variant. For precise specs, consult the latest AO3480 datasheet from AOS or distributor catalogs. If you share the intended package or operating voltage/current, I can narrow down the exact variant.
Pinout
- Pin count: 3 (SOT-23 package)
- Function: N-channel enhancement-mode MOSFET (G = gate, D = drain, S = source) used as a switching device.
- Function: N-channel enhancement-mode MOSFET (G = gate, D = drain, S = source) used as a switching device.
Manufacturer
AO3480 is manufactured by Alpha and Omega Semiconductor (AOS). AOS is a fabless semiconductor company that designs and markets power MOSFETs and analog/mixed-signal ICs for power management and switching applications.
Application
AO3480 is a high-speed, logic-level N-channel power MOSFET used for switching and power-management tasks. Typical applications include:
- DC-DC converters (buck/boost) and synchronous rectification
- High-side/low-side load switches and power-distribution switches
- Battery-powered devices (laptops, tablets, handhelds)
- Automotive electronics (DC-DC, motor drivers, lighting control)
- Industrial and solar power management (inverters, charge controllers)
- PWM power stages and motor control
Note: Suitable for compact, efficient switching in many PMIC and power-supply designs.
