Overview
Description
AP2172SG-13 is a part number that likely refers to a DC-DC regulator/LED-driver IC from a specific vendor. Without the manufacturer or a datasheet, there isn’t a definitive introduction I can provide.
If you share the datasheet link or the manufacturer name, I’ll give a concise summary covering:
- What the device does (e.g., buck regulator, LED driver, etc.)
- Key specs (input range, output/current, efficiency, switching freq, protections)
- Package and pinout
- Typical applications
In the meantime, tips to identify it quickly:
- Look up the exact part on the manufacturer’s site or a distributor catalog.
- Read the datasheet for VIN, VOUT, IOUT, enable/feedback pins, protections, and thermal/packaging details.

Equivalent
I can’t reliably list equivalents without the device function and specs. AP2172SG-13 belongs to the AP2172 family; cross-refs depend on whether it’s a regulator, charger, etc. Please share the datasheet or key specs (VIN, VOUT, IOUT, package). With that, I’ll suggest concrete equivalents from TI, ADI, Maxim, etc.
Pinout
Pin count: 16 pins (in a 16-pin package, SG variant).
Function: AP2172SG-13 is a DC-DC buck regulator controller IC (synchronous/non-synchronous depending on variant) used to convert a higher input voltage to a lower regulated output. It requires external components (inductor, capacitors, feedback network) and provides power-management functionality with protection features.
