The LT3991EDDPBF is a monolithic buck (step-down) regulator from Linear Technology, designed for efficient power conversion. It features a wide input voltage range from 4.3V to 55V and can deliver up to 1.2A of output current.
Key electrical characteristics include an ultralow quiescent current of 2.8µA when regulating, and a low shutdown current of 700nA. The switching frequency is adjustable from 200kHz to 2MHz, and it can be synchronized within the 250kHz to 2MHz range. The device has an internal compensation and a saturating switch design with 0.44Ω on-resistance.
The output voltage can be adjusted from 1.19V to 30V. The LT3991EDDPBF is available in small, thermally enhanced 10-pin MSOP and 3mm x 3mm DFN packages, suitable for surface mount applications.
This regulator is designed for applications requiring high efficiency and low power consumption, such as battery-powered devices and automotive systems.
