Microchip MCP16251 | Demoboard ARD00797

Description

Microchip’s MCP16251 device is a compact, high-efficiency, fixed-frequency, synchronous step-up DC-DC Converter. The very low quiescent current makes it ideal for battery-powered applications. Furthermore, the device provides a true output disconnect feature while in shutdown (EN = GND). The MCP16251 device consumes less than 0.6 μA from the battery when in the shutdown state. The MCP16251 automatically selects the best operating mode for efficiency: Pulse-Width Modulation (PWM) or Pulse-Frequency Modulation (PFM). The device has a very low (4 μA) quiescent current (not switching, measured at output), a wide input voltage range (0.35 to 5.5V) and a low start-up voltage (0.82V) at a 1 mA load current.
