Mosfet, can be usefull for the DC-DC conversion
between 2.5V and 1.5V at 2A in portable applica-
tions reducing the power dissipation.
L6932 is available in 1.5V, 1.8V, 2.5V and adj ver-
sion from 1.2V and ensure a voltage regulation ac-
curacy of 1%.
The current limit is fixed at 2.5A to control the cur-
rent in short circuit condition within ±8%. The cur-
rent is sensed in the power mos in order to limit the
power dissipation.
The device is also provided of a thermal shut down
that limits the internal temperature at 150°C with
an histeresys of 20°C. L6932 provides the Enable
and the Power good functions.
