Analog Devices Inc. LTC3355 Demo Board DC2040A is a 12V to 4V/1A regulator with an integrated super cap charger and backup boost regulator featuring the LTC3355EUF. The LTC3355 charges up a 3F supercapacitor from the output when the 12V input is available. When the 12V input fails, the backup boost regulator supplies the output until the energy in the supercapacitor is depleted.
