Q1: What is overcurrent protection in boost buck converter?
When the output current is greater than the set value, the output voltage value decreases gradually until no voltage is output. (When the starting load is too large, it will start the overcurrent protection and no output voltage. Common inductive loads, such as motors, pumps, etc.)
Q2: Explanation of over-temperature protection in buck and boost converter
When the chip temperature of the dc buck boost converter is greater than 150°C, the power converter stops working and no voltage is output. (Note: This temperature does not mean the working environment temperature)
Q3: Short circuit protection
Under normal use, an instantaneous short circuit of the positive and negative terminals of the output will not cause damage to the DC-DC power converter. (Note: This protection includes all step-down, step-up and isolation products, step-up products do not have this protection).
