NCP1271D65R2G

The NCP1271D65R2G is a soft-skip mode Standby Pulse Width Modulation (PWM) Controller with adjustable skip level and external latch. It allows for excellent stand by power consumption by use of its adjustable esoft-skip mode and integrated high voltage startup FET. This proprietary Soft-Skip also dramatically reduces the risk of acoustic noise. This allows the use of inexpensive transformers and capacitors in the clamping network. 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.

• Fixed-frequency current-mode operation with ramp compensation and skip cycle in standby condition
• Timer-based fault protection for improved overload detection
• Soft-skip mode technique for optimal noise control in standby
• Internal high-voltage startup current source for lossless startup
• 5% Current limit accuracy over the full temperature range
• Adjustable skip level
• Internal latch for easy implementation of overvoltage and overtemperature protection
• Frequency jittering for softened EMI signature
