On-Time

Operation

The RT7255 is a synchronous step-down converter

with advanced constant on-time control mode. Using

the ACOT control mode can reduce the output

capacitance and fast transient response. It can

minimize the component size without additional

external compensation network.

UVLO Protection

To protect the chip from operating at insufficient supply

voltage, the UVLO is needed. When the input voltage

of VIN is lower than the UVLO falling threshold voltage,

the device will be lockout.

Thermal Shutdown

Current Protection

When the junction temperature exceeds the OTP

threshold value, the IC will shut down the switching

operation. Once the junction temperature cools down

and is lower than the OTP lower threshold, the

converter will autocratically resume switching.

The inductor current is monitored via the internal

switches cycle-by-cycle. Once the output voltage drops

under UV threshold, the RT7255 will enter hiccup

mode.
