AP3190数据手册Diodes中文资料规格书

描述 Description

 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 multimode control scheme, AP3190 can also achieve high-conversion efficiency with full-load conditions.

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 (60kHz) and low line (80kHz). At light load or no load, the IC will operate in burst mode to minimize power consumption.

The AP3190 provides comprehensive protections without additional circuitry. It includes VCC overvoltage 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.

AP3190 is packaged in SOT26 (Type SM).
