LT3652EMSE#PBF Datasheet PDF - Linear Technology

●The LT3652EMSE#PBF is a complete monolithic step-down Battery Charger IC, operates over a 4.95 to 32V input voltage range. It 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 14.4V can be programmed with a resistor divider. It employs an input voltage regulation loop, which reduces charge current if the input voltage falls below a programmed level, set with a resistor divider. When the LT3652EMSE#PBF is powered by a solar panel, the input regulation loop is used to maintain the panel at peak output power.
