RT4803 is a boost regulator that's designed to provide the minimum output
|
|
voltage, even if the input voltage is lower than the required voltage. It
|
|
supports boost and auto bypass mode that depends on the difference between the
|
|
input and output voltage. If the input is lower than the output, mode will
|
|
transform to boost mode. Otherwise, turn on bypass switch to enter bypass mode.
