ZHCSMV3A December 2020 – December 2021 TPS552882-Q1
PRODUCTION DATA
In addition to the average inductor current limit, the TPS552882-Q1 implements the output short-circuit protection by entering the hiccup mode. When the output short circuit happens, the TPS552882-Q1 goes into output current limit first. If the output voltage is below 0.8 V and the average inductor current is above the setting value, the TPS552882-Q1 shuts down the switching for 76 ms (typical) and restarts the soft start repeatedly. The hiccup mode helps reduce the total power dissipation on the TPS552882-Q1 in the output short-circuit or overcurrent condition.
