Device description
15/37
The L6732 can sink or source current after the soft-start phase (see Figure 9.). If an over
current is detected during the soft-start phase, the device provides a constant-current-
protection. In this way, in case of short soft-start time and/or small inductor value and/or high
output capacitors value and so, in case of high ripple current during the soft-start, the
converter can start in any case, limiting the current (see section 4.6 monitoring and
protections) but not entering in HICCUP mode.
During normal operation, if any under-voltage is detected on one of the two supplies, the SS
pin is internally shorted to GND and so the SS capacitor is rapidly discharged.
