DESCRIPTION
The LT®3383 is a plete 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 (So C) rails and three 300m A LDO regulators for low noise analog supplies.
Regulator start-up is sequenced by connecting outputs to enable pins in the desired order. A master power-on pin is provided to initiate pin-strapped power-on sequences.
A status pin is available to indicate regulator...
