n Side Wettable 40-Lead 6mm × 6mm QFN Package The LT®3380 is a complete power management solution
for advanced portable application processor-based systems. The device contains four synchronous step-down
DC/DC converters for core, memory, I/O, and system onchip (SoC) rails and three 300mA LDO regulators for low
noise analog supplies. An I2C serial port may be used
to control regulator enables, power-down sequencing,
output voltage levels, dynamic voltage scaling, operating
modes, and status reporting. APPLICATIONS The device is available in a 40-lead 6mm × 6mm QFN with …
