The LTC3417AEFE#PBF is a dual constant frequency, synchronous step-down DC/DC converter from Linear Technology, designed for medium power applications. It operates from a 2.25V to 5.5V input voltage range and features adjustable output voltages from 0.8V to 5V. Each channel provides a guaranteed minimum output current of 1A and 1.5A respectively. The device supports programmable switching frequencies, with options including 1.5MHz or adjustable from 0.6MHz to 4MHz, allowing for the use of small external components.
Key features include high efficiency up to 95% in Burst Mode operation, internal synchronous power switches that eliminate the need for external Schottky diodes, and short-circuit protection. It also offers low quiescent current of 125µA in sleep mode and ultralow shutdown current below 1µA. The device supports low dropout operation with a 100% duty cycle and includes a Power Good output.
This regulator is available in a 20-lead TSSOP package with an exposed pad, suitable for surface mounting. Its design is well-suited for applications such as GPS/Navigation, digital cameras, PC cards, wireless and DSL modems, and general-purpose point-of-load DC/DC conversion.
