Synchronous Rectification IC Includes Reference Design Board

The IRDCSYN2 reference design board for the IR1176 application-specific synchronous rectification IC is rated at 3.3 Vdc and 20A with an efficiency of 90%. The reference design includes a fully functional synchronous rectification circuit, complete with a bill of materials, schematics, application notes and Gerber file.
The board measures 3.25" x 2.7" x 0.75" and the IR1176 IC simplifies and improves isolated dc/dc converters with voltage output down to 1.5V, powering telecom and broadband network servers. When used with the company's dc/dc converter-specific HEXFET power MOSFETs, the chip enhances 1.5V and 1.8V dc/dc converter efficiency ratings. At 40A, in-circuit efficiency is 86% for 1.8V and 85% for 1.5V output circuits with 48V input. The chip also controls gate drive circuits to minimize losses in secondary-side, isolated dc/dc converter synchronous rectification MOSFETs. The reference design is priced at $376.
