LTC3589EUJ-1 Description

Short technical summary and product information.

The LTC3589EUJ-1 is a comprehensive power management solution designed for ARM and ARM-based processors and advanced portable microprocessor systems. This integrated circuit features three high-efficiency step-down DC/DC converters, a 1.2A buck-boost converter, and three 250mA LDO regulators, providing multiple independent rails for core, memory, SoC, and analog supplies.

Control is managed via an I2C serial port, allowing for adjustment of output voltage levels, dynamic voltage scaling, operating modes, and status reporting. The device also supports pushbutton ON/OFF control with system reset functionality and flexible pin-strap sequencing. It is available in a low-profile 40-pin 6mm x 6mm exposed pad QFN package, suitable for space-constrained applications.

Key electrical specifications include selectable switching frequencies of 2.25MHz or 1.12MHz and a low standby current of 8µA. The step-down converters offer currents up to 1.6A, while the buck-boost converter handles up to 1.2A. The LDO regulators provide 250mA, with an always-alive LDO capable of 25mA.

Applications for the LTC3589EUJ-1 include handheld instruments, scanners, portable industrial devices, automotive infotainment, medical devices, high-end consumer devices, and multirail systems. It is designed to support processors like Freescale i.MX53/51, Marvell PXA, and OMAP processors.
