CT is the the capacitance value on the CT pin (in pF)

•

The units for the constant a are µs/V. The units for the constant b are µs/(V × pF).

Rise time can be calculated by multiplying the input voltage by the slew rate. Table 2 contains rise time values

measured on a typical device. Rise times shown below are only valid for the power-up sequence where VIN is

already in steady state condition before the EN/UVLO pin is asserted high.
