VMP3110-High Efficiency DC-DC Module:VMP3110 is a compact, ultra high efficiency low voltage DC-DC power supply module. It integrated all necessary components in a small (0.7”x0.6”x0.14”) package. The internal DC-DC converter can convert 3.6V-5.5V input voltage to 1.0-3.3V, up to 1.0A current. The small size, low profile and high efficiency makes it is the ideal choice for applications which size and energy requirement is critical.
