AP3190P中文资料PSR Controller with Peak Load Mode数据手册Diodes规格书

描述 Description

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.

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.

The AP3190P provides comprehensive protections without additional circuitry. It contains VCC over voltage protection, output over voltage protection, output short circuit protection, etc.

The AP3190P has adjustable OTP by external NTC resistor. It consumes less than 65mW input power at no load condition with high line voltage.

The AP3190P is packaged in SOT26 (Type SM).
