Using a zero voltage switching technique, the RD212 200-W DC/DC converter reference design from Fairchild Semiconductor can operate at an efficiency of up to 94 percent. With user's guide, application notes and schematics, the design uses the FEB212 evaluation board and features the FSFR2100 FPS power switch, PFM controller, and a high-voltage gate driver with two fast-recovery MOSFETs. Offering a 24-V output at 8 A, the design also offers over-voltage, overload, thermal, and overcurrent protection. From $68.75.
