LT3652HVEDD#PBF

LT®3652HV is a complete monolithic step-down battery charger that operates over a 4.95V to 34V input range. This 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. This employs an input voltage regulation loop, which reduces the charge current if the input voltage falls below a programmed level, set with a resistor divider. Application includes solar-powered applications, remote monitoring stations, portable handheld instruments, 12V to 24V automotive systems, and battery charging from the currently limited adapters.
