DescripTion
The
LTC
®
3589
is a complete power management solu-
tion 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 sup-
plies. An I
2
C 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.
Regulator start-up is sequenced by connecting outputs to
enable pins in the desired order or programmed via the
I
2
C port. System power-on, power-off, and reset functions
are controlled by pushbutton interface, pin inputs, or I
2
C
interface.
The LTC3589 supports i.MX53/51, PXA and OMAP pro-
cessors 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

How to store the parameters set by the user (without losing data after power failure) when designing a controller using a single-chip microcomputer?
I recently designed a controller using AT89C51. There are several parameters that users need to set on site. It is required that they should not be lost after the power is turned off and can be read o...
