Pin Function
Transition Threshold. Connect a resistor divider to let the RT6296E into power
saving mode under light loads. Connect to PVCC to force RT6296E into CCM.
Power Input. Support 6V to17V Input Voltage. Must bypass with a suitable large
ceramic capacitor at this pin.
Switch Node. Connect to external L-C filter.
System Ground.
Bootstrap Supply for High-Side Gate Driver. Connect a 0.1F ceramic capacitor
between the BOOT and SW pins.
Soft-Start Control Input. SS control the soft-start period. Connect a capacitor from
SS to GND to set the soft-start period.
5V Bias Supply Output. Connect a minimum of 0.1F capacitor to ground.
Feedback Voltage Input. The pin is used to set the output voltage of the converter
to regulate to the desired voltage via a resistive divider. Feedback reference =
0.8V.
