The NCP1271D100R2G from ON Semiconductor is a fixed-frequency, current-mode PWM controller designed for offline switch flyback converters. This device features a 100kHz operating frequency and supports an input voltage range of 10V to 20V.
Key electrical characteristics include an 80% duty cycle and fault protection for current limiting, overload, overvoltage, and short circuits. The controller also offers features like adjustable skip level, internal latch for protection implementation, and frequency jittering for softened EMI signature. It is capable of +500 mA/−800 mA peak current drive and can achieve standby power below 100 mW.
Packaged in a 7-SOIC surface mount package, the NCP1271D100R2G is suitable for applications such as AC-DC adapters for notebooks and LCD monitors, offline battery chargers, and consumer electronic appliances like STBs and DVD players. Its design prioritizes ruggedness and component cost-effectiveness.
