AP3190

PRIMARY SIDE REGULATED SWITCHING MODE POWER SUPPLY CONTROLLER

Description

Pin Assignments

The AP3190 is a high-performance offline PSR AC/DC power supply

controller. It is specially designed for the applications that require the

higher efficiency at light load and cost effectiveness. Using the multi-

mode control scheme, AP3190 can also achieve high-conversion

efficiency with full-load conditions.

OTP

At heavy load and low line, AP3190 will operate in QR mode to

achieve high performance. When the load is decreasing, it will enter

fixed switching frequency operating mode. To optimize product

performance, the fixed frequency is different in high line (60kHz) and

low line (80kHz). At light load or no load, the IC will operate in burst

mode to minimize power consumption.

OUT

VCC

GND

SOT26 (Type SM)

The AP3190 provides comprehensive protections without additional

circuitry. It includes V_CCovervoltage protection, output overvoltage

protection, output short-circuit protection, etc. AP3190 has adjustable

OTP by external NTC resistor. Besides, AP3190 consumes less than

65mW input power at no-load condition with high-line voltage.

Applications



Adapters/chargers

Smart speakers

Set-top box power supplies

Network adaptors

AP3190 is packaged in SOT26 (Type SM).

Features



Burst Mode Operation for Light Load High Efficiency (at 10%

Loading > 80%)



Primary Side Control for Eliminating Optocoupler

65mW No-Load Input Power

Adjustable Overtemperature Protection

Multiple QR/AM Mode to Improve Audio Noise and Efficiency

QR for Higher Efficiency and Better EMI

Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
