AP2205-W5-7

AP2205-W5-7 is a DC-DC switching regulator (buck) IC in the AP2205 family. It’s used to convert a higher input voltage to a lower, stable output for power rails in portable and embedded devices. The “-W5-7” suffix typically denotes a packaging/tape-reel variant; the exact pinout and electrical specs vary by supplier, so always check the datasheet for your lot.
Key points:
- Integrated high-side switch and regulation control
- Adjustable output via a feedback network; enables/shutdown control
- Protection features: current limit, thermal shutdown, overvoltage protection
- High efficiency in a compact package
Typical use:
- Choose inductor, input/output capacitors per reference design
- Connect VIN, GND, VOUT, FB (voltage feedback), and EN
- Follow layout guidelines for best efficiency and stability
For precise VIN range, VOUT, max load, switching frequency, and pinout, consult the specific vendor’s datasheet for AP2205-W5-7.

AP2205-W5-7 is a 7-pin device. It is a single-channel buck DC-DC switching regulator (step-down converter). For exact pinout (pin names by pin number), please provide the manufacturer/datasheet, since pin assignments vary by package and vendor.

- Manufacturer: Anpec Electronics Corp. (ANPEC).
- What kind of company: A Taiwan-based fabless semiconductor company that designs and sells power-management ICs (PMICs), including DC-DC converters, MOSFETs, and related PMIC components.
