The AP3190T 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 AP3190T can also achieve high conversion efficiency with full load conditions. At heavy load and low line, the AP3190T 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 line (60kHz) and low line (80kHz).
The AP3190T is traditional PSR CVCC controller. The controller samples the VCS peak current and the demagnetization pulse to regulation the output current. The current and output power setting can be adjusted externally by the sense resistor at CS pin.
The AP3190T provides comprehensive protections without additional circuitry. It contains VCC overvoltage protection, output overvoltage protection, output short circuit protection, etc.
The AP3190T has adjustable OTP by external NTC resistor. It consumes less than 65mW input power at no load condition with high line voltage.
The AP3190T is packaged in SOT26 (Type SM).
