Description
The RM6203 is a current mode PWM switching power supply controller that specifically designed for AC/DC converter with high performance versus cost ratio. It provides continuous output power up to 12W in the broad voltage range of 85V – 265V.Its optimized and highly reasonable circuit design has made it possible to minimize the total cost of the
product.
This power supply controller could be used in typical flyback circuit topology to constitute simple AC/DC converter. The internal initiating circuit of RM6203 has been designed
with a unique means of current sink to complete the startup using the amplifying function of the power switching tube. This will significantly reduce the power consumption of the start-up resistor; and when the output power becomes smaller, RM6203 will automatically lower its operating frequency to enable very low standby power consumption.

Features:
■ Built-in 700V high voltage power switching tube with minimal external parts count
■ Latched PWM and pulse-by-pulse current limiting inspection
■ Reduced frequency at low output with standby power consumption below 0.25W
■ Built-in slope and feedback compensation function
■ Separate upper limit current inspection controller to handle timely the over-current and overload of the controller
■ Turn off periodic bias output of the emitter to improve the voltage resistance of the power tube
Applications:
■ Power Adaptors(traveling chargers ,stand-alone power set)
■ Internal power supply for Energy-Saving Appliances (such as electromagnetic oven, microwave oven and etc.)
