Frequently asked questions
Can it replace an SG3524?
They are similar PWM controllers, but internal details and pinouts can differ. Compare the two datasheets before substituting one for the other.
What external parts are needed?
You need timing components for the oscillator, a feedback network for the error amplifier, and a power stage (transistor or MOSFET) with a suitable gate driver.
