LA5779N - Monolithic Linear IC Separately-excited Step-down Switching Regulator

of Functional Settings Calculation equation to set the output voltage This IC controls the switching output so that the VOS pin voltage becomes 1.23V (typ).

The equation to set the output voltage is as follows: R2 VO = 1+ × 1.23V(typ) R1 The VOS pin has the inrush current of 1µA (typ).

Therefore, t
