of Functional Settings 1.Start delay function The SS pin has the internally-connected 22µA (typ) constant-current supply.When the voltage of SS pin exceeds the threshold voltage, the regulator starts operation.As the threshold is 0.62V(typ), the start delay time can be calculated as follows: ex.For setting at 1µF Td = C × V 1µ × 0.62 = = 28.2 msec 22µ i 1.5V 2.Soft start function The internal PWM waveform has the voltage value as shown in the right.If down-conversion from the voltage of VIN
