LTC1871EMS in Linear Tech / ADI LT Series Family
The LTC1871EMS series, manufactured by Analog Devices (formerly Linear Technology), is a versatile current-mode switching regulator controller designed for boost, flyback, and SEPIC topologies. Operating from a wide input voltage range, these controllers utilize a constant frequency architecture that can be synchronized to an external clock. The family is distinguished by its No RSENSE technology, which uses the power MOSFET's on-resistance to sense current, eliminating the need for a discrete sense resistor and improving overall efficiency.
Variants in This Sub-Family
Variants within the LTC1871EMS sub-family typically differ in their lead-free status and packaging options. The 'PBF' suffix denotes lead-free construction, while variations in the 'TR' prefix indicate tape-and-reel shipping formats. While the core electrical characteristics like the 36V maximum input and internal gate driver remain consistent, certain versions may be optimized for specific temperature grades such as industrial or automotive ranges.
