AP22800HB-7

AP22800HB-7 is a DC-DC buck regulator IC from Anpec (AP) in a compact HB-7 package. It’s used to convert a higher input voltage to a stable, lower output in space-constrained power supplies.
Key points:
- 7-pin HB package variant
- Designed for efficient step-down regulation
- Features typically include enable/soft-start, and protection functions such as overcurrent/short-circuit and thermal shutdown
- Output voltage is adjustable via external feedback (and some variants may offer fixed options)
- Suitable for portable, embedded, and compact automotive/industrial applications
For exact electrical specifications (input range, output voltage options, maximum current, switching frequency), consult the official AP22800HB-7 datasheet from Anpec.

I need the datasheet or manufacturer to be exact. AP22800HB-7 is not unique across vendors, and pin count/function can vary by variant. If this is Anpec’s AP22800HB-7, it is typically a 1-channel high-side load switch with input, output, ground, enable, and protection/current-limit pins in a 7-pin package. Please provide the datasheet/link for precise pinout and function.
