NCP1219AD100R2G Description

Short technical summary and product information.

The NCP1219AD100R2G from ON Semiconductor is a 7-pin current-mode PWM controller. It is designed for applications requiring excellent standby power consumption, utilizing an adjustable skip mode and an integrated high-voltage startup FET.

 

Key electrical specifications include a fixed frequency of 100kHz, an input voltage range of 9.9V to 20V, and an 80% duty cycle. The controller offers features such as Dynamic Self Supply (DSS) to eliminate the need for an auxiliary winding, timer-based fault protection for improved overload detection, and cycle skip to reduce input power in standby mode. It also provides latch and auto-recovery overload protection options.

 

This device is suitable for AC-DC adapters for notebooks and LCD monitors, offline battery chargers, and consumer electronic appliances like set-top boxes and DVD players. It is available in a 7-SOIC package and operates within a temperature range of -40°C to 150°C (TJ).

 

The NCP1219 series is pin-to-pin compatible with the existing NCP12XX series, facilitating upgrades. It also features frequency modulation for a softened EMI signature and an accurate current limit detector with ±5% tolerance.
