Datasheet Summary
Powered by GS/AI

The NCP1219BD65R2G is a PWM controller designed for offline switcher applications, featuring fixed-frequency current-mode operation at 65 kHz. It incorporates a dynamic self-supply mechanism that eliminates the need for an auxiliary winding, simplifying transformer design, particularly beneficial in applications with varying output voltage such as battery chargers. The controller includes adjustable skip mode for reduced input power during standby, timer-based fault protection for improved overload detection, and options for latch and auto-recovery overload protection. It also features an internal high voltage startup circuit, accurate current limit detection with a tolerance of ±5%, and frequency modulation to minimize EMI. The device is packaged in a SOIC-7 format and is Pb-free, making it suitable for a range of applications including AC-DC adapters, offline battery chargers, and consumer electronic appliances.
