LA5752MP Datasheet (Sanyo Semicon Device) - Separately-Excited Step-Down Switching Regulator

LA5752MP, Separately-Excited Step-Down Switching Regulator

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.
