概述
Description
AOZ1336DI is a power-management IC from Alpha & Omega Semiconductor (AOS), part of the AOZ133x family. It is used as a DC-DC switching regulator (buck) in compact boards to derive a lower voltage from a higher input.
Key points:
- Integrated switching regulator plus MOSFETs (typical synchronous buck) with external inductor, capacitors, and feedback network.
- Features usually include adjustable output via a feedback divider, enable/shutdown control, soft-start, and protection (overcurrent/short-circuit, overtemperature, UVLO).
- Common applications: power rails for mobile devices, FPGAs/GPUs, and other consumer/telecom electronics.
- Package options are small (e.g., 8-pin, QFN/SOIC variants); check the exact pinout in the datasheet.
Important: exact electrical specs (input range, output voltage, current capability, switching frequency) vary by variant and package. For precise details, consult the AOZ1336DI datasheet and application notes.
