The MIC2877 is a compact and highly efficient 2MHz synchronous boost regulator with a 6.5A (typical) switch. It features a bidirectional true load disconnect function that prevents any leakage current between the input and output when the device is disabled (EN = GND), protecting the input supply and improves the start-up performance. The MIC2877 has the input voltage range between 2.5V and 5.5V and provides a 2A output continuous current for VIN = 3V and VOUT = 5V.
