Ultra High Efficiency 94-96%
High-Speed Response Step-Down DC-DC Converter
VSV - m3,m6,m8
VSV-m3, m6, m8 is an ultra small size (15×24×4mm size) and light weight (2.6g) step-down DC-DC converter, which has achieved maximum 26W.
Since it can correspond from ultra low output voltage of 1.0V, it can be used for the latest DSP, ASIC applications. Due to high-speed response,
high efficiency by synchronous rectification circuit technology, saving space by no external components, an excellent performance beyond our
common sense has been achieved.
