It integrates an advanced current-mode pulse width modulator (PWM) and an avalanche-rugged 700 V SenseFET in a single package, allowing auxiliary power designs with higher standby efficiency, reduced size, improved reliability, and lower system cost than prior solutions. Fairchild Semiconductor’s mWSaver™ technology offers best-in-class minimum no-load and light-load power consumption. An innovative Ax-CAP® method, one of the five proprietary mWSaver™ technologies, minimizes losses in the EMI filter stage by eliminating the X-cap discharge resistors while meeting IEC61010-1 safety requirements. mWSaver™ Green Mode gradually decreases switching frequency as load decreases to minimize switching losses. Proprietary asynchronous jitter decreases EMI emission and built-in synchronized slope compensation allows stable peak-current-mode control over a wide range of input voltage. The proprietary internal line compensation ensures constant output power limit over the entire universal line voltage range. Requiring a minimum number of external components, DNP015 provides a basic platform that is well suited for the cost-effective flyback converter design with low standby power consumption. Applications General-purpose switched-mode power supplies (SMPS) and flyback power converters, including:  Auxiliary Power Supply for PC, Server, LCD TV, and Game Console  SMPS for VCR, SVR, STB, DVD, and DVCD Player, Printer, Facsimile, and Scanner  General Adapter  LCD Monitor Pow [...]
