6 FAQs about [Low Voltage DC Capacitors]

Are small capacitors a good choice?

Smaller capacitors are acceptable for light loads, or in applications where ripple is not a concern. The control-loop architecture developed by Texas Instruments allows the designer to choose the output capacitors and externally compensate the control loop for optimum transient response and loop stability.

Can a designer downsize the output capacitor?

The designer can downsize the output capacitor to save money and board space. The basic selection of the output capacitor is based on the ripple current and ripple voltage, as well as on loop stability considerations. The effective series resistance (ESR) of the output capacitor and the inductor value directly affect the output ripple voltage.

How to choose a capacitor for a step-down DC-DC converter?

In succession to selection of inductors, we turn to a discussion of capacitor selection. Capacitors that are essential for a step-down DC-DC converter include output capacitors and input capacitors. We begin by explaining output capacitors. Similarly to inductor selection, the choice of capacitor is also very important.

How much capacitance should a capacitor have?

Given the high load current, a large capacitance, in the range of 20-200mF, is required, depending on the specific loading condition. This requires the use of a large number of capacitors with an optimal ratio of capacitance, ESR and ripple current of the capacitor.

What factors should be considered when selecting a capacitor?

The following three factors are important when selecting the output capacitor. Of course the voltage and ripple current applied to a capacitor must be below the maximum ratings for the capacitor. The ESR is an important parameter that determines the output ripple voltage associated with the inductor current, and must be studied carefully.

Which input capacitance should a converter use?

The power source is a rechargeable battery and despite its relatively low internal resistance, the choice of input capacitance is critical to the proper operation of the converter. Given the high load current, a large capacitance, in the range of 20-200mF, is required, depending on the specific loading condition.
