Product Details

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.
