High-Speed Response Non-Isolated POL DC-DC Converter
9.5A BSV Series
BSV Series is a small (33×22.5×7mm), 31.35W output power step-down DC-DC
converter. With ultra-low output voltage from 0.8V, it can support the latest FPGA, DSP,
ASIC applications. High efficiency and ultra-high-speed response with synchronous
rectification have been achieved along with space-saving without external parts. This
product will exceed your expectations in all aspects.
