NCP1219BD100R2G Description

Short technical summary and product information.

The NCP1219BD100R2G is an integrated circuit from On Semiconductor, functioning as an offline switching controller for flyback topologies. It features fixed-frequency current-mode operation at 100kHz, with options for ramp compensation. The device supports a wide supply voltage range from 9.9V to 20V and offers an 80% duty cycle.

 

Key features include dynamic self-supply to eliminate auxiliary windings, timer-based fault protection for overload detection, and cycle skip for reduced standby power. It also provides adjustable skip level and a latch input for overvoltage and overtemperature protection. The controller is capable of 500 mA/800 mA peak source/sink current drive and includes an internal high voltage startup circuit.

 

This component is housed in a 7-SOIC package and is suitable for surface mount applications. Its operating temperature range is -40°C to 150°C (TJ). The NCP1219BD100R2G is designed for applications requiring ruggedness and component cost efficiency, such as AC-DC adapters for notebooks and LCD monitors, and offline battery chargers.

 

The device is Pb-Free and Halogen Free/BFR Free. It offers RoHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1.
