AT1382B
Preliminary Product Information
4-Channel DC-DC Converter for DSC
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)
−( ^Ts )
V_CS = 0.7 × (1 − e ) ^R×Cs
R = ^{33.6 ×117.6} KΩ
33.6 + 117.6
The soft start function of CH1 to CH4 are the same. It could be disabled soft start function by
floating CS pin.
6. Setting the output voltage
