Thus these EA pins 1 and 2 can be effectively configured for implementing an automatic the output voltage correction of a converter. It's a simple op amp arrangement inside the IC which controls the PWM of the IC outputs at Pin#11 and Pin#14. Pin#1 is the inverting input while pin#2 is the complementary non-inverting input. Pin#1 and #2 (EA inputs): These are inputs of the built-in error amplifier of the IC. The IC SG3525 is a single package multi function PWM generator IC, the main operations of the respective pin outs are explained with the following points: Pinout Diagram of the IC SG3525 PinOut DescriptionĪ practical implementation of the following pinout data may be understood through this inverter circuit
