Overview
High performance current mode PWM controller. Designed for high price/performance ratio AC/DC converter design. Provided in a wide voltage range of 85V-265V The continuous output power rate up to 12W, the peak output power rate can reach 18W. Optimized and rational circuit design combined with high performance and price ratio The bipolar manufacturing process of the company, to the greatest extent, saves the overall product This. The power controller can work in typical flyback circuit topology.

FEATURE
● Built-in 800V high-voltage power switch tube
● Latch pulse width modulation, pulse-by-pulse current limit detection
● Light load frequency reduction function, standby power consumption can be lower than 0.3W
● Built-in proportional drive and feedback compensation function
● Independent upper limit current detection controller, real-time handling of the controllers overcurrent and overload
● The off-cycle emitter bias output improves the withstand voltage of the power tube
● Built-in temperature-compensated current limiting resistor, precise current limiting
● Built-in thermal protection circuit
● Use the amplifying effect of the switch power tube to complete the start, reducing the power consumption of the starting resistance
● Very few peripheral components
● Low starting current and low working current
● VCC overvoltage automatic limit
● Wide voltage continuous output power can reach 12W, peak output power can reach 18W  

APPLICATION area
● Adapter ADAPTOR (such as travel charger, external power box, etc.)
● OPENFRAME (such as DVD, DVB, etc.)
