To operate with a 5-V input, two resistors need to be changed. R10 (RKFF) sets the voltage ramp amplitude and needs to be reduced to 53.6 kΩ to lower the UVLO to 3.9 V for 5-V operation. In addition, a 330-kΩ resistor should be added at R15 to prevent an internal race condition during soft start.(1)
