LTC3531EDD in Linear Tech / ADI LT Series Family
The LTC3531EDD family, developed by Analog Devices (formerly Linear Technology), consists of synchronous buck-boost DC/DC converters designed for efficient power delivery from input voltages above, below, or equal to the output. These devices are optimized for single-cell Li-Ion or multicell alkaline/NiMH applications where maintaining a stable rail is critical despite varying battery voltage. With a compact footprint and high efficiency, they minimize heat dissipation and extend battery life in space-constrained portable electronics.
Variants in This Sub-Family
Variants within the LTC3531EDD sub-family are primarily differentiated by their output voltage configurations and packaging standards. Most common is the LTC3531EDD-3.3, which provides a fixed 3.3V rail to reduce external component count. Standard PBF suffixes indicate lead-free, RoHS-compliant DFN packages. While the core architecture remains consistent, minor variations in temperature grading may exist to suit specific industrial or commercial operating environments.
