DC763A - LTC4065EDC Demo Board | Vin=3.75V-5.25V, 650mA Standalone Li-Ion Linear Battery Charger

Demonstration circuit DC763 is a complete constant-current, constant-voltage battery charger designed to charge single-cell lithium-ion batteries. The DC763 is based on the LTC4065 that is available in a 2mm ´ 2mm DFN package and features an exposed bottom-side metal pad for soldering to the PC board. The LTC4065 features an internal MOSFET with thermal feedback loop that regulates the charge current to limit the die temperature during high power operation or high ambient thermal conditions. The preset float voltage is 4.2V with 0.6% accuracy, and the constant charge current is 650mA.
