The LT3383 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 on-chip (SoC) rails and three 300mA 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 undervoltages. If an overtemperature or low supply fault is detected all regulators are disabled during the fault condition.

The device is available in a 40-lead 6mm × 6mm QFN with wettable flanks for optical inspection.

Product Detail

DC2984A is a multi-output power management solution demonstration circuit, featuring the LT3383. It contains two 2.5A synchronous step-down DC-DC regulators, two 1.5A synchronous step-down DC-DC regulators and three 300mA LDO regulators. All the regulators can be enabled via its corresponding enable pins. The startup sequence of the regulators can be programmed by connecting the outputs of the regulators to the enable pins in desired order.
