The LTC3589EUJ#TRPBF is a DC/DC integrated power solution from Analog Devices. It features an input voltage range from 2.25V to 6V and an output voltage range from 0.6V to 5.25V. It has a single high-efficiency integrated buck regulator.
It provides a 250-kHz fixed frequency current mode control architecture, with adjustable output voltage and integrated passive load-sharing capability. The device also has over-current protection, short-circuit protection, thermal shutdown, and over-temperature protection.
In addition, it has an enabling pin for external power management and soft-start for reduced inrush current. The integrated solution reduces external component count, board space, cost, and inductor size compared to discrete solutions. It is a 16-pin, thermally enhanced, 4mm × 4mm QFN package.
