Microchip Technology MCP16415
The MCP1641X Step-up DC-DC Converters family provides an automatic input-to-output voltage bypass operation, which helps optimize battery utilization and achieve high efficiency, while the nominal voltage of fresh batteries remains in the same range with the converter’s output value. The MCP1641X can be powered by either single-cell, two-cell alkaline/NiMH batteries or single-cell Li-Ion/Li-Polymer batteries. The start-up voltage is easily programmed by a resistive divider connected to the UVLO pin.FEATURES
