NCP1219AD65R2G General Description

The NCP1219 represents a new, pin to pin compatible, generation of the successful 7-pin current mode NCP12XX product series. The controller allows for excellent standby power consumption by use of its adjustable skip mode and integrated high voltage startup FET. Internal frequency jittering, ramp compensation, timer-based fault detection and a latch input make this controller an excellent candidate for converters where ruggedness and component cost are the key constraints.
The Dynamic Self Supply (DSS) drastically simplifies the transformer design in avoiding the use of an auxiliary winding to supply the NCP1219. This feature is particularly useful in applications where the output voltage varies during operation (e.g. battery chargers). Due to its high voltage technology, the IC can be directly connected to the high voltage dc rail.

Key Features

Fixed-Frequency Current-Mode Operation with Ramp Compensation (65 kHz and 100 kHz Options)
Dynamic Self Supply Eliminates the Need for an Auxiliary Winding
Timer-Based Fault Protection for Improved Overload Detection
Cycle Skip Mode
Latch and Auto-Recovery Overload Protection Options
Internal High Voltage Startup Circuit
Accurate Current Limit Detector (±5%)
Adjustable Skip Level
Latch Input for Easy Implementation of Overvoltage and Overtemperature Protection
Frequency Modulation for Softened EMI Signature
500 mA/800 mA Peak Source/Sink Current Drive Capability
Pin to Pin Compatible with the Existing NCP12XX Series
This is a Pb-Free and Halide-Free Device

Application

AC-DC Adapters
Consumer Electronic Power Supplies
