Device description
40
If the failure event occurs on the SW pin and the IOVC threshold is reached the regulator is
latched off. To restart the DC/DC regulator a power-down and power-up cycle of device
supply voltage (VM) is mandatory.
If the failure event occurs on the regulator output (VDDA pin) and the voltage goes below
the UVLO threshold (VDDOff), the regulator restarts with a new soft-start sequence until the
OC condition is removed. In this case the current in the coil is limited by ISW.peak.
The DC/DC regulator embeds a thermal protection as described in Section 6.1.2.
