5mm x 5mm 3-Phase DC/DC Controller Operates up to 140ºC
MILPITAS, CA – March 23, 2010 – Linear Technology Corporation introduces the LTC3731H, a PolyPhase® high efficiency (up to 95%) synchronous DC/DC controller with guaranteed operation for junction temperatures as high as 140ºC offered in a 5mm x 5mm QFN package. This rugged DC/DC controller is expandable from 3- to 12-phase operation for 60A to 240A power supply designs. The precision ±5% output phase current matching simplifies thermal management by evenly spreading the heat among the output stages. Applications include high current ASIC and FPGA supplies, power distribution buses, automotive engine control units and network servers.
