The device contains four synchronous step-down DC/DC converters for core, memory, I/O, and system on-chip (SoC) rails and three 300mA LDO regulators for low noise analog supplies.
The LTC3676-1 has a ±1.
5A buck regulator configured to support DDR termination plus a VTTR reference output.
An I2C serial port is used to control regulator enables, power-down sequencing, output voltage levels, dynamic voltage scaling, operating modes and status reporting.
Regulator start-up is sequenced by connecting outputs to enable pins in the desired order or via the I2C port.
System power-on, power-off and reset functions are controlled by pushbutton interface, pin inputs, or I2C.
The LTC3676 supports i.
MX, PXA and OMAP processors with eight independent rails at appropriate power levels.
Other features include interface signals such as the VSTB pin that toggles between programmed run and standby output voltages on up to four rails simultaneously.
