DC-DC Converter

BSV-H Series is a small (27.0x16.5x4.0mm), light (2.8g), 52.8W output power

step-down DC-DC converter. With ultra-low output voltage from 0.8V, it can support

the latest DSP, ASIC applications. High efficiency and ultra-high-speed response with

synchronous rectification have been achieved along with space-saving SMD

packaging without external parts. This product will exceed your expectations in all

aspects.
