| Part Number | NCP1282 |
| Manufacturer | ON Semiconductor |
| Title | High Performance Active Clamp/Reset PWM Controller |
| Description | Pin Symbol Description 1 Vin Connect the input line voltage directly to this pin to enable the internal startup regulator. A constant current s. |
| Features |
of the NCP1282 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.
