soft-start timing can be programmed by the external

capacitor between SS pin and GND. The Chip provides

a 11

A charge current for the external capacitor.

Over Current Protection

RT7296C provides cycle-by-cycle over current limit

protection. When the inductor current peak value

reaches current limit, IC will turn off High Side MOS to

avoid over current.

Under Voltage Protection (Hiccup Mode)

RT7296C provides Hiccup Mode of Under Voltage

Protection (UVP). When the FB voltage drops below

function will be triggered and the IC will shut down for a

period of time and then recover automatically. The

Hiccup Mode of UVP can reduce input current in

short-circuit conditions.

Thermal Shutdown

Thermal shutdown is implemented to prevent the chip

from operating at excessively high temperatures. When

the junction temperature is higher than 150

C, the chip

will shutdown the switching operation. The chip is

automatically

re-enabled

when

the

junction

temperature cools down by approximately 20

C.
