Overview
The LT3582EUD#PBF is an I²C programmable boost and single inductor inverting DC/DC converter manufactured by Analog Devices Inc. It operates within a 2.475 V to 5.5 V input voltage range and provides two independent outputs, including a fixed 12 V output. The device delivers up to 200 mA of output current with a typical quiescent current of 325 uA. It functions at a switching frequency of 100 kHz and supports both boost and inverting topologies. The component is housed in a 16-lead QFN package and is rated for operation between -40°C and +125°C.
Feature Summary
- Integrates I²C programmability for flexible configuration of operating parameters
- Utilizes a single inductor architecture to implement both boost and inverting conversion topologies simultaneously
- Features low quiescent current consumption to enhance efficiency in battery-powered applications
Applications
- Portable electronic devices requiring multiple supply rails from a single source
- Systems needing simultaneous positive and negative voltage generation
- Battery-operated equipment prioritizing power management efficiency
Procurement Notes
Verify the specific suffix and tape/reel or tube packaging requirements against the official datasheet before ordering. Confirm that the intended application environment falls within the specified temperature range. Ensure that the I²C interface compatibility matches the system controller. Check for any recent lifecycle notices regarding availability or obsolescence status directly from the manufacturer.
Selection Notes
Select this component when a design requires generating both boosted and inverted voltages using a minimal number of passive components. The I²C interface allows for dynamic adjustment of settings, which is beneficial for systems requiring programmable power sequences. Consider the thermal performance of the QFN package relative to the expected load current and ambient conditions.
Part Context
This part belongs to the LT3582 series of power management integrated circuits designed for efficient energy conversion. It is categorized under switching voltage regulators and PMICs. The device is distinct from standard buck converters due to its dual-topology capability and digital control interface, offering a compact solution for complex power distribution needs in small form factor designs.
Replacement Considerations
Consult the official Analog Devices documentation for verified substitute part numbers. Cross-reference pinouts and electrical specifications carefully if considering alternative models from other manufacturers.
