LT1954EDD#PBF – LINEAR

The Linear Technology LT1954EDD#PBF is a monolithic, step-down switching regulator specifically designed for high-current, high-frequency applications. It utilizes a current mode architecture enabling excellent transient response and loop stability. The device integrates a power Schottky diode and a robust internal MOSFET, minimizing external component count and simplifying design. Output Voltage Rating is adjustable via external resistors, typically ranging from 1.23V to the input voltage, but is internally limited to 5V. It delivers a continuous Output Current Rating of 2.5A. Housed in a thermally enhanced 3mm x 3mm DFN (Dual Flat No-leads) Package Type, it offers excellent heat dissipation. Operating Temperature Range is specified from –40°C to 125°C, making it suitable for demanding environments. Common applications include point-of-load regulation in telecom infrastructure, industrial power supplies, and automotive systems. Its small size, integrated features, and high efficiency provide significant board space savings and simplify thermal management in densely populated circuit boards.
