LTM4641IY in Linear Tech / ADI LT Series Family
The LTM4641IY is a high-efficiency 10A DC/DC step-down μModule regulator manufactured by Analog Devices (formerly Linear Technology). Designed for high-reliability systems, this power module integrates the switching controller, power FETs, inductor, and support components into a compact BGA package. It is specifically engineered to protect downstream loads from catastrophic overvoltage conditions caused by internal or external faults, making it a critical component for high-value processor and FPGA power stages.
Variants in This Sub-Family
The LTM4641IY sub-family variants primarily differ based on their lead-frame finishes and thermal testing grades. The PBF suffix denotes a lead-free, RoHS-compliant finish using SAC305 solder balls. While the core electrical specifications remain consistent across the series, designers should select specific ordering codes based on their manufacturing process requirements, such as BGA ball composition and operating temperature range compliance for industrial versus commercial environments.
