AP3917C

UNIVERSAL AC VOLTAGE STEP DOWN POWER SWITCHER

Description

Pin Assignments

The AP3917C is a universal AC voltage step-down power switcher,

which is specially designed for home appliance and IoT applications

with non-isolated buck solution or offline flyback solution.

(Top View)

Drain

The device integrates a 650V high-performance Power MOSFET.

Coordinating with a single-winding inductor, it uses fewer external

components and provides a low Bill of Material (BOM) cost solution.

The AP3917C can achieve excellent regulation and high-power

efficiency. The peak current and switching frequency continuously

reduce as the load decreases, so it can get excellent efficiency

performance at light load and improve the overall system efficiency.

SO-7

The AP3917C has multiple protection features to enhance system

safety and reliability. It has over-temperature protection, under-

voltage lock function, output short protection, overload protection,

and open-loop protection.

The AP3917C is available in the SO-7 package.
