LM2574, LM2574HV SNVS104C – JUNE 1999 – REVISED APRIL 2013 www.ti.com Figure 24. Adjustable Output Voltage Version As in any switching regulator, layout is very important. Rapidly switching currents associated with wiring inductance generate voltage transients which can cause problems. For minimal inductance and ground loops, the length of the leads indicated by heavy lines should be kept as short as possible. Single-point grounding (as indicated) or ground plane construction should be used for best results. When using the Adjustable version, physically locate the programming resistors near the regulator, to keep the sensitive feedback wiring short. Table 1.
