DC569A, Demo Board based on LTC4054ES5-4.2, 4.25 to 10Vin, Jumper selectable, 450mA, 600mA, Li-Ion Battery Charger

DC569A, Demonstration Circuit is a single cell Li-ion linear charger in a SOT-23. Charge rates as high as 600mA can be achieved due to the LTC4054 internal die temperature control loop that prevents excessive PCB heating under worst-case conditions. The user is provided with a control jumper to select between OFF/450mA/600mA charge rates. The reduced charge rate is suitable for USB applications. A charge LED illuminates while the charger is charging the battery
