LT1615IS5 in Linear Tech / ADI LT Series Family
The LT1615IS5 is a micropower, constant off-time DC/DC boost converter sub-family from Analog Devices (formerly Linear Technology). Specifically designed for low-power applications, these devices feature a low quiescent current of only 20µA and a built-in 36V switch. They are primary choices for generating higher output voltages from single-cell Li-Ion or multi-cell alkaline batteries in space-constrained embedded systems where high efficiency at light loads is critical for battery longevity.
Variants in This Sub-Family
Variants within the LT1615 series primarily differ based on their internal current limits and package temperature ratings. For instance, the LT1615-1 offers a lower 75mA current limit compared to the standard 300mA version, allowing for smaller inductors in ultra-low-power designs. Packaging suffixes like #PBF or #TRMPBF indicate lead-free finishes and tape-and-reel quantities, while the 'I' grade specifies a wider industrial operating temperature range.
