Portable Equipment General Description
The MIC2877 is a compact and highly efficient 2 MHz
synchronous boost regulator with a typically 6.5A
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), it protects the input supply and improves
the start-up performance.
The MIC2877 has the input voltage range between …
