Description
The DNP015 is a next-generation, Green Mode
Fairchild Power Switch (FPS) that incorporates
Fairchild’s innovative mWSaver™ technology, which
dramatically reduces standby and no-load power
consumption, enabling conformance to all worldwide
Standby Mode efficiency guidelines. 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 Power / Open-Frame SMPS
