ADI LTC3589IUJ-2#PBF

手持式/移动设备，OMAP™8µA2.7V ~ 5.5V

Overview

The LTC3589IUJ is a complete power management solution for ARM and ARM-based processors and advanced portable microprocessor systems. The device contains three step-down DC/DC converters for core, memory and SoC rails, a buck-boost regulator for I/O at 1.8V to 5V and three 250mA LDO regulators for low noise analog supplies. An I2C serial port is used to control enables, output voltage levels, dynamic voltage scaling, operating modes and status reporting. Differences between the LTC3589, LTC3589-1, and LTC3589-2 are summarized in Table 1.

The LTC3589IUJ supports i.MX53/51, PXA and OMAP processors with eight independent rails at appropriate power levels. Other features include interface signals such as the VSTB pin that simultaneously toggle up to four rails between programmed run and standby output voltages. The device is available in a low profile 40-pin 6mm × 6mm exposed pad QFN package.
