CM6561A - No Bleed Resistor 8-PIN Transition Mode SINGLE PFC
The CM6561A is pin to pin compatible with L6561 and L6562.
There are several important improvements: 1.
IAC (pin 3), Multiplier input pin, Current input instead of Voltage input; it will enhance input current THD and the system will be less sensitive the noise.
The system can reduce one resistor bet
