6 / 10 page L6932 6/10 Adjustable version Figure 8. Demoboard Layout (Adjustable Version) COMPONENTS SELECTION Input Capacitor The input capacitor value depends on a lot of factors such as load transient requirements, input source (battery or DC/DC converter) and its distance from the input cap. Usually a 47 µF is enough for any application but a much lower value can be sufficient in many cases. Output Capacitor The output capacitor choice depends basically on the load transient requirements. Tantalum, Speciality Polimer, POSCAP and aluminum capacitors are good and offer very low ESR values. Multilayer ceramic caps have the lowest ESR and can be required for particular applications. Nevertheless in several applications they are ok, the loop stability issue has to be considered (see loop stability section). Below a list of some suggested capacitor manufacturers.
