Applications and typical circuits

If you want, I can:

Note: Some references mention additional pins (up to 8) for specific variants or synchronization inputs, so always check your physical chip's configuration.

Check the startup resistor connected to Pin 4. If it burns open, the VCC capacitor cannot charge, preventing the IC from turning on.

While common in older hardware, it is often treated as an "obsolete" or "hard-to-find" part by modern distributors, though it is still widely available from specialty suppliers like Jotrin Electronics or Veswin . ⚠️ Common Use Cases

The IC includes several critical safety mechanisms to protect the power supply and connected loads: Over-Voltage Protection (OVP): Shuts down the IC if output voltage exceeds safe limits Over-Current Protection (OCP): Limits the peak current through the MOSFET Thermal Shutdown (OTP): : Combines a power MOSFET and a current-mode

: Current-mode PWM control paired with built-in frequency jittering to substantially lower Electro-Magnetic Interference (EMI) emissions.
