AOZ1282CI-2

AOZ1282CI-2 is a power-management IC from Alpha & Omega Semiconductor (the AOZ family). It is a compact, high-efficiency synchronous buck regulator used to convert a higher DC input to a lower, stable output for digital and mixed-signal circuits. The device typically provides integrated power MOSFETs and control logic, enabling a simple external-resistor set for the output voltage and fast transient response. Key features often include adjustable output, enable/shutdown, protection such as undervoltage lockout, over-current/short-circuit protection, and thermal shutdown; some variants also include soft-start. The “CI-2” suffix denotes a specific package/version (RoHS/lead-free). Applications include portable power rails, embedded systems, and consumer electronics. For exact electrical specs (input range, allowable output voltages, switching frequency, package type), consult the official AOZ1282CI-2 datasheet and related application notes.

Pin count: 8 pins (8-pin package, e.g., SO-8/QFN-8).
Function: A synchronous buck DC-DC converter (step-down regulator) used for power-management applications.

- Manufacturer: Alpha and Omega Semiconductor (AOS).
- Company type: A US-based semiconductor company that designs and manufactures power management ICs and power MOSFETs, providing high-efficiency power conversion solutions for computing, consumer electronics, automotive, and industrial applications.
