LT3652IDD in Linear Tech / ADI LT Series Family
The LT3652IDD is a complete monolithic step-down battery charger from Analog Devices (formerly Linear Technology), designed for a wide range of battery chemistries. Operating over a 4.95V to 32V input range, it provides a constant-current/constant-voltage charge characteristic with a programmable charge current up to 2.2A. It is specifically engineered to maximize power extraction from solar panels using its innovative input voltage regulation loop, which maintains the panel at its peak power point.
Variants in This Sub-Family
The LT3652IDD variant specifically denotes the industrial temperature range version (-40°C to 125°C) in a 3mm x 3mm DFN-12 package. While other members of the LT3652 family share the same silicon core, variants like the LT3652EDD target commercial temperatures, and the LT3652MSE uses a thermally enhanced MSOP package. Pin-compatible versions may differ in lead finish (e.g., #PBF for lead-free) and tape-and-reel packaging options.
