DC1229B-A

DC1229B-A is an evaluation board to evaluate 2A monolithic Li-Ion battery charger featuring the LT®3650EDD-4.2/LT3650EDD-4.1. The LT3650 is a complete mid-power Li-Ion battery charger that can operate over a wide input voltage range. The circuit provides CC/CV charging with a maximum charge current externally programmable up to 2A. A precondition feature trickle charges a low-voltage battery and bad battery detection provides a signal if the battery doesn’t respond to preconditioning. The LT3650EDD is available in a 12-lead (3mm × 3mm) DFN surface mount package with an exposed pad.

• Input voltage range from 7.5V to 32V
• 3.7V to 4.24V VOUT
• Output float voltage 4.2V/4.1V at constant voltage mode
• 2A output current limit ILIM at RRNG = 20Kohm
