RM6203
High Performance Current Mode PWM Switching Power Supply controller
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.
When the power tube stops, the internal circuit will turn
the power tube reverse bias to greatly raise the voltage
resistant capacity of OC pin. This will ensure the safety of the
power tube. The internal design of the RM6203 is also
provided with over-load and saturation preventive function
capable of preventing disorders such as overload, transformer
saturation and output short-circuit, so as to increase the
reliability of the power supply. A voltage reference of 2.5V is
also integrated in the RM6203 to provide accurate power
supply to the clock circuit, and the clock frequency may be set
by external timing capacitance. Presently, standard DIP8
package and environmental friendly lead-free package in
compliance with European standard can be supplied.
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
Built-in thermal protective circuit
Complete start-up using amplification of the switching
power tube to reduce the power consumption of the start-up
resistor more than ten times
Automatic VCC over-voltage limit
Broad voltage output power up to 5W and narrow voltage
output power up to 8W
Applications
Power Adaptors(traveling chargers ,stand-alone power
set)
Internal power supply for Energy-Saving Appliances (such
as electromagnetic oven, microwave oven and etc.)
