Application of LTM8064

Question

Datasheets on LTM8064 show a circuit of 2 supercapacitors. Can I apply this circuit to 16 supercapacitors? What is
the advantage of this circuit over a transistor in key mode and shunting resistor balance circuit?

Chaz · Answer

How many supercaps you can series for the example configuration will depends on the output voltage and current requirements, etc. In theory, it may be fine for more than two (or even 16?) stacked. Make sure any time, especially during transients, all LTM8064 pin maximum rating requirements have been met. For example, Vout pin should always be lower than 40V. The voltage across each supercap is regulated by a module separately, therefore, the voltages are well controlled. Thanks.
