Description
1 Vin Connect the input line voltage directly to this pin to enable the internal startup regulator.
A constant current source supplies current from this pin to the capacitor connected to the VAUX pin, eliminating the need for a startup resistor.
Features
- of the NCP1562 are soft- stop and a cycle skip current limit with a time threshold. Soft- stop circuitry powers down the converter in a controlled manner if a severe fault is detected. The cycle skip detector enables a soft- stop sequence if a continuous overcurrent condition is present. Additional features found in the NCP1562 include line feedforward, frequency synchronization up to 1.0 MHz, cycle- by- cycle current limit with leading edge blanking (LEB), independent under and overvoltage dete.
