AP3190P
IOT PSR MULTI-MODE CONTROLLER
Description
Pin Assignments
The AP3190P is a high-performance offline PSR AC/DC power-
supply controller. It is specially designed for the application that
require the higher efficiency at light load and cost effectiveness.
Using the multi-mode control scheme, the AP3190P can also achieve
high conversion efficiency with full load conditions.

CS
At heavy load and low line, the AP3190P will operate in QR mode to
achieve high performance. When the load decreasing, it will enter into
fixed switching frequency operating mode. To optimize product
performance, the fixed frequency is different in high (60kHz) and low
line (80kHz).

At light load or no load the IC will operate in burst mode to minimize
power consumption.
The AP3190P is designed to authorize a transient peak power
excursion for peak load. It means the OCP reference can be
increased to 1.75 times when the peak event disappears.
SOT26 (Type SM)
The AP3190P provides comprehensive protections without additional
circuitry. It contains VCC over voltage protection, output over voltage
protection, output short circuit protection, etc.
Applications
IoT offline powers
Smart speakers
The AP3190P has adjustable OTP by external NTC resistor. It
consumes less than 65mW input power at no load condition with high
line voltage.
Set-top box power supplies
Network adaptors
The AP3190P is packaged in SOT26 (Type SM).
