Fairchild Semiconductor 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. 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. 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 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.
