3 / 5 page LA5754 No.A0951-3/5 VO = 1+ × 2.66V(typ) R2 R1 Block Diagram Application Circuit Example VIN SWOUT VOS GND SS L1 47 µH C1 1000 µF C2 1000 µF D1 SBD LA5754 C3 1 µF R2 R1 Notes: C3 is for the soft start function. Delete C3 and keep the SS pin open when the soft function is not necessary. Calculation equation to set the output voltage This IC controls the switching output so that the VOS pin voltage becomes 2.66V (typ). The equation to set the output voltage is as follows: The VOS pin has the inrush current of 1µA (typ). Therefore, the error becomes larger when R1 and R2 resistance values are large.
