AOZ1282CI-2

AOZ1282CI-2 is a high‑efficiency synchronous buck DC‑DC regulator from Alpha & Omega Semiconductor. It integrates the main power MOSFETs and control circuitry to convert a higher input voltage to a lower, stable output rail with minimal external parts.
Key points:
- Purpose: provides a regulated low-voltage supply for digital logic, FPGAs/ASICs, CPUs, telecom, and automotive electronics.
- Architecture: synchronous buck with built‑in high‑ and low‑side MOSFETs, enabling compact designs and higher efficiency.
- Features: adjustable output via external feedback divider; enable/shutdown pin; soft‑start; overcurrent and thermal protection.
- Packaging: CI variant in a compact, leadless package suitable for space‑constrained boards.
- Typical usage: connect Vin to the regulator, place the external inductor and output capacitors per the datasheet, use the feedback network to set Vout, and drive EN to enable.
Note: exact electrical specs (Vin range, supported Vout, switching frequency, efficiency) vary by variant. Refer to the AOZ1282CI‑2 datasheet for precise values and typical application circuits.

Here are the typical features of AOZ1282CI-2 (dual synchronous buck regulator in one package):
