Designed with an internal 50m Ω N-channel 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.
