7 / 9 page 7 GM7130HV 3A STEP DOWN VOLTAGE SWITCHING REGULATORS Preliminary Information Test Circuit and Layout Guidelines Careful layout is important with any switching regulators. Rapidly switching currents associated with wiring inductance generate voltage transients which can cause problems. To minimize inductance and ground loops, the lengths of the leads indicated by heavy lines in Figure 1&2 below 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, place the programming resistors as close as possible to GM2576, to keep the sensitive feedback wiring short.
