PROCESSORS I/O

CHIPSET AND RAM SUPPLY

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.

DESCRIPTION

The L6932 Ultra Low Drop Output linear regulator

operates from 2V to 14V and is able to support 2A.

Designed with an internal 50mΩ N-channel
