LT3652HV 1A Solar Panel Powered 3-Stage 12V Lead-Acid Fast/Float Charger

1A Solar Panel Powered 3-Stage 12V Lead-Acid Fast/Float Charger; 1A Charger Fast Charges with CC/CV  Characteristics Up to 14.4V; When Charge Current Falls to 0.1A Charger Switches to 13.5V Float Charge Mode;  Charger Re-Initiates 14.4V Fast Charge Mode i

The LT3652HV is a complete monolithic step-down battery charger that operates over a 4.95V to 34V input range. The LT3652HV provides a constant-current/constant-voltage charge characteristic, with maximum charge current externally programmable up to 2A. The charger employs a 3.3V float voltage feedback reference, so any desired battery float voltage up to 18V can be programmed with a resistor divider.
