Fairchild Semiconductor (NYSE: FCS) makes it easier for
designers to develop more efficient power supplies and meet
stringent energy efficiency specifications with its 200W DC-DC
power supply reference design. The RD212 reference design offers
high efficiency (up to 94 percent) and low noise characteristics
due to its zero voltage switching (ZVS) technique. It provides a
24V output at 8A and offers numerous protection functions. These
protection functions (over-voltage protection (OVP), overload
protection (OLP), over-current protection (OCP), abnormal
over-current protection (AOCP) and internal thermal protection
(TSD)) protect the power supply from adverse electrical events.
With user�s guide, application notes and schematics, it can quicken
the design cycle and drive higher levels of efficiency in power
supply designs. The RD212 reference design is an optimal tool for
simplifying design, increasing efficiency and conserving space in
flat panel TVs, PCs, servers, street lighting and various off-line
power supplies.
The RD212 features the FSFR2100, a green FPS� power switch that
integrates a pulse-frequency-modulation (PFM) controller with a
high-voltage gate driver, two fast recovery MOSFETs (FRFET�s) and
important protection features such as soft-start and burst
operation into a thermally-efficient SIP package. This switch
offers a soft-switching approach that reduces switching losses,
even though the actual switching frequency increases. Through its
ZVS technique, switching losses are further reduced allowing the
switch to handle up to 200W without a heat sink.
Fairchild offers a comprehensive portfolio of reference designs
that simplify system design, reduce board space, ensure system
reliability and accelerate time-to-market. With the worldwide
energy concerns, designers are increasingly relying on
semiconductor suppliers to come up with innovative ways to improve
efficiency during normal operation as well as during standby mode.
By offering a production-ready design, reference designs are
instrumental in enabling OEMs to shorten their design time and
bring their system to the market quicker.
Complementing the RD212 reference design is the FEB212
evaluation board that contains a user�s guide, application notes
and a full tested board to evaluate your design.
