normal functionality (assuming that the short condition is removed), it is necessary to restart
the converter through an enable transient.
Short-circuit protection (SCP)
When short-circuit occurs, the device is able to detect the voltage difference between V
and V
stages of the device are turned off. This status is maintained, avoiding current flowing to the
load. A new ENABLE transition is needed to restart the device. During startup the short-
circuit protection is active.
Fast discharge
When ENABLE turns from high to low level, the device goes into shutdown mode LX1 and
LX2 stop switching. If the FD pin is low, a resistor of about 400 Ω is connected between
