6 FAQs about [7660 energy storage capacitor selection]

What is an energy storage capacitor?

Capacitors for Energy Storage Applications Energy storage capacitors can typically be found in remote or battery powered applications. Capacitors can be used to deliver peak power, reducing depth of discharge on batteries, or provide hold-up energy for memory read/write during an unexpected shut-off.

What are energy storage capacitor specifications?

Capacitor specifications of capacitance, DC leakage current (DCL), equivalent series resistance (ESR), size, etc. are typically room temperature measurements under a very specific test condition. Furthermore, energy storage capacitors will often be set up in some parallel/series combination that can pose unique challenges or unexpected behaviour.

Which capacitors are suitable for energy storage applications?

Tantalum and Tantalum Polymer capacitors are suitable for energy storage applications because they are very efficient in achieving high CV. For example, for case sizes ranging from EIA 1206 (3.2mm x 1.6mm) to an EIA 2924 (7.3mm x 6.1mm), it is quite easy to achieve capacitance ratings from 100μF to 2.2mF, respectively.

Why does a 7660 have a diode in series?

To prevent destructive latchup, a diode was added in series with the output of previous 7660 designs when operated at elevated temperature or supply voltage. While this prevented latchup, it also lowered the available output voltage and increased the output series resistance.

Which MLCC capacitors are suitable for energy storage applications?

Barium Titanate based MLCC characteristics1 Figure 1. BaTiO3 Table 2. Typical DC Bias performance of a Class 3, 0402 EIA (1mm x 0.5mm), 2.2μF, 10VDC rated MLCC Tantalum and Tantalum Polymer capacitors are suitable for energy storage applications because they are very eficient in achieving high CV.

How does the LMC7660 work?

The LMC7660 is a switched capacitor voltage converter that uses its built-in oscillator to switch 4 power MOS switches and charge two inexpensive electrolytic capacitors. This allows it to operate over full temperature and voltage range with low quiescent current and high power efficiency, without needing an external diode.
