5. Soft start setting
The soft start operation is determined by the capacitor connected to the CS1~CS4 terminal.
Consider the input voltage and load current to design the soft start time.
The soft start time until the DC/DC converter output voltage reaches 95%. It can calculate the soft
start time Ts (s).
Ts (s) = 0.084 * C
S (μF)
The soft start function of CH1 to CH4 are the same. It could be disabled soft start function by
floating CS pin.
