(11) Overcurrent protection circuit/Output short protection circuit
The overcurrent protection circuit is built into output, and functions as the current limit.
Note that if the protection circuit operates more than a specified time period (when the output short-circuit protection
circuit detects a load short or other similar state) the output will be latched OFF.
Output is restored when the EN block is activated again, or when UVLO is deactivated. Although the protection circuits
effectively prevent IC destruction under fault conditions, they should not be employed continuously.
(12) Selection of inductor
Please use an inductor with a series resistance element (DCR) under 0.2ฮฉ. Note that use of a high DCR inductor will
cause an inductor loss, resulting in decreased voltage output. Should this condition continue for a specified period (soft
start time + timer latch time), output short circuit protection will be activated and output will be latched OFF. When using
an inductor over 0.2ฮฉ, be careful to ensure adequate margins for variation between eternal devices and this IC, including
transient as well as static characteristics.
