DC1976A-B - LTC3676EUJ-1 Demo Board | PMIC with DDR DC/DC for Application Processors: 4 Bucks, 4 LDOs, I2C Control (req DC2026)

Demonstration circuit 1976A-B is a multioutput power supply with a pushbutton controller and I2C, featuring the LTC®3676EUJ-1. The LTC3676EUJ-1 has four synchronous buck regulators (1.5A x 2 and 2.5A x 2), an always-on LDO (25mA) and three 100mA LDO regulators. One buck is configured to provide 1/2VIN at 1.5A for DDR memory needs. The 2.7V to 5.5V input voltage range of the LTC3676EUJ-1 is ideal for single-cell Li-Ion/Polymer battery applications.
