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鈩?P-channel MOSFET and, in order to improve

the efficiency, a variable frequency control is imple-

mented.
