PWM Controller with
Adjustable Skip Level and
External Latch Input
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.
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 Reduces Input Power in Standby 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
• These are Pb−Free Devices
• These are Halide−Free Devices
Typical Applications
• AC−DC Adapters for Notebooks, LCD Monitors
• Offline Battery Chargers
• Consumer Electronic Appliances STB, DVD, DVDR

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
