The LTC3612HUDC#PBF from Analog Devices is a high-efficiency, monolithic synchronous step-down DC/DC converter. It is designed for applications requiring a 3A output current and features an input voltage range of 2.25V to 5.5V, making it suitable for single Li-Ion battery or fixed low voltage input systems.
This converter utilizes a current mode, constant frequency architecture and supports adjustable switching frequencies up to 4MHz, allowing for the use of small surface mount inductors. It boasts up to 95% efficiency and 100% duty cycle capability for low dropout operation, extending battery life in portable systems. The device also offers low quiescent current in Burst Mode operation (70µA) and very low shutdown current (≤1µA).
The LTC3612HUDC#PBF is available in a thermally enhanced 20-pin QFN (3mm x 4mm) or TSSOP package, suitable for surface mount applications. Its internal synchronous switch eliminates the need for an external catch diode, saving board space and simplifying design.
Key electrical characteristics include a 3A maximum output current, a 2.25V to 5.5V input voltage range, and an adjustable switching frequency up to 4MHz. The output voltage accuracy is ±1%, with a minimum output voltage down to 0.6V. It also supports DDR memory mode with an output current of ±1.5A.
