Buck Boost Solar Charge Controller

The device operates from input voltages above below or equal to the output voltage and can be powered by a solar panel.

Buck boost solar charge controller.

Linear technology corporation introduces the ltc4020 an advanced high voltage power manager and multi chemistry battery charger designed to efficiently transfer power from a variety of sources to a system power supply rail and a battery. The lt8490 is a buck boost switching regulator battery charger that implements a constant current constantvoltage cccv charging profile used for most battery types including sealed lead acid sla flooded gel and lithium ion. I was trying to make the diy solar boost converter with mppt charge controller with the following components. This design uses a buck boost topology and allows the pv solar voltage to be above below or equal to the battery voltage.
