LT1613CS5 in Linear Tech / ADI LT Series Family
The LT1613CS5 sub-family, manufactured by Analog Devices (formerly Linear Technology), consists of high-frequency, current-mode DC/DC converters housed in small SOT-23 packages. These 1.4MHz constant-frequency switching regulators are engineered for space-constrained applications requiring boost, flyback, or SEPIC configurations. Capable of generating up to 30V at the output, the family is primarily utilized for local supply generation from single-cell Li-Ion batteries or 5V rails in compact portable electronics.
Variants in This Sub-Family
The LT1613CS5 series primarily differentiates through its packaging and environmental ratings. While the core 1.4MHz switching architecture remains consistent, variants like the LT1613CS5#TRMPBF denote specific tape and reel packaging standards and lead-free compliance (PBF). Engineers should note that while the electrical characteristics across the sub-family are largely uniform, thermal performance may vary slightly based on the specific ThinSOT package variant and PCB landing pattern used.
