De- signed with an internal 50m Ω N-channel Mosfet, can be usefull for the DC-DC conversion be- tween 2.5V and 1.8V at 2A in portable applications reducing the power dissipation. L6932 is available in 1.8V, 2.5V and adj version from 1.2V and ensure a voltage regulation accuracy of 1%. The current limit is fixed at 2.5A to control the current in short circuit condition within ±8%. The current 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.
