DESCRIPTION
The L6920 is a high efficiency step-up controller re-
quiring only three external components to realize the
conversion from the battery voltage to the selected
output voltage.
The start up is guaranteed at 1V and the device is op-
erating down to 0.6V.
Internal synchronous rectifier is implemented with a
120m
P-channel MOSFET and, in order to improve
the efficiency, a variable frequency control is imple-
mented.
