The LTC3589UJ-1 is a comprehensive power management solution from LT, engineered for advanced portable microprocessor systems and ARM-based processors. This IC integrates three step-down DC/DC converters, a buck-boost regulator capable of handling I/O voltages from 1.8V to 5V, and three 250mA LDO regulators for low-noise analog supplies.
Key features include an I2C serial port for control of enables, output voltage levels, dynamic voltage scaling, and status reporting. The device supports flexible pin-strap sequencing for regulator start-up and offers pushbutton ON/OFF control with system reset functionality. It operates with an input voltage range of 2.7V to 5.5V and supports selectable switching frequencies of 1.12MHz or 2.25MHz.
The LTC3589UJ-1 is available in a low-profile 40-pin 6mm x 6mm exposed pad QFN package, suitable for surface mounting. Its design makes it ideal for applications such as handheld instruments, scanners, portable industrial devices, automotive infotainment, and medical devices requiring multi-rail power management.
Additional features include an always-alive 25mA LDO regulator and a low standby current of 8µA, contributing to power efficiency in portable applications.
The input voltage range is 2.7 V to 5.5 V.
The switching frequency can be selected between 1.12 MHz and 2.25 MHz.
The standby current is 8 µA.
The LTC3589UJ-1 is available in a 40-pin QFN package.
The Moisture Sensitivity Level is 1 Unlimited.
