3652HV中文资料Power Tracking 2A Battery Charger数据手册ADI规格书

描述 Description

DESCRIPTION
The LT®3652HV 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.FEATURES
