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. <Features> - Latest Power-IC adopted - Adjustable Output - High-speed Response - Non-Isolated Type Converter - Efficiency 94%, 96% - Ultra Minimum Size - ON/OFF Control - Operating Temp. -40°C to +85°C - Heat Sink not required - High Reliability, High Performance - The Latest Technology, Synchronous Rectification Circuit - Additional external capacitor not required - Short-Circuit, Over-Current Protection - RoHs Compliance <Model, Rating> Model VSV-3.3S3R0M VSV-3.3S6R0M VSV-3.3S8R0M Table 1 Rating Input Voltage Vdc Rating Output Voltage Vdc 5.0 (3.0-5.5) 3.3 (1.0-3.3) Rating Output No-Load Input Ripple Noise Current Current mVpp(typ.)
