AOZ5507QI

AOZ5507QI is a synchronous buck DC-DC converter from Alpha & Omega Semiconductor (AOZ family). It integrates high-side and low-side MOSFETs and a PWM controller to efficiently convert a higher input voltage to a lower, stable output for digital rails. Key features typically include adjustable Vout via external feedback resistors, enable and soft-start, and protection like overcurrent/short-circuit, overvoltage, undervoltage lockout, and thermal shutdown. It is packaged in a compact QFN with an exposed pad, suitable for power-management modules in CPUs/GPUs, telecom, industrial, and automotive applications. For exact specs—input voltage range, output voltage options, switching frequency, and maximum current—refer to the AOZ5507QI datasheet and reference designs.

I don’t have enough detail to give reliable equivalents. Please confirm the full AOZ5507QI part number and key specs (function, voltage/current ratings, package) or share the datasheet; then I can list accurate drop-in replacements.
