LA5771 General Description

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. F.
