Overview
The LT3471EDD is a dual switching regulator manufactured by Analog Devices Inc., housed in a DFN-10 package. It integrates two independent converters: a boost converter and an inverting (buck-boost) converter, both operating at a fixed 1.2MHz switching frequency. The device accepts an input voltage range of 2.4V to 16V. Each output channel provides up to 1.3A of output current, with the boost section capable of delivering up to 40V. The quiescent current is specified at 2.5mA. It supports shutdown functionality and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates a boost converter and an inverting converter in a single compact package
- Supports high output currents of 1.3A per channel for demanding power applications
- Operates at a fixed 1.2MHz switching frequency to minimize external component size
- Includes shutdown control to reduce supply current during low-power states
Applications
- Generating multiple positive supplies from a single Li-ion battery source
- Creating dual tracking power rails including negative voltages from lithium cells
- Powering portable electronic devices requiring compact DC-DC conversion solutions
Procurement Notes
Verify the specific suffix against official Analog Devices documentation to confirm pinout compatibility and thermal characteristics. Confirm RoHS compliance status through the manufacturer's current datasheet revision. Ensure the DFN-10 package footprint matches your PCB design constraints before finalizing procurement decisions.
Selection Notes
Select this component when space-constrained designs require two independent regulated outputs from a single input source. It is suitable for applications needing both positive and negative rails or dual positive voltages. Consider the 1.2MHz frequency trade-off between efficiency and passive component size relative to lower-frequency alternatives.
Part Context
This part belongs to the LT3471 series of dual switching regulators designed for high-density power management. It is distinct from other Linear Technology parts like the LT3971 buck regulators or MAX3471 transceivers. The device addresses the need for integrated power solutions in mobile and industrial systems where board real estate is limited.
Replacement Considerations
LT3471EDD#PBF is the full lead-free variant of this component. Verify cross-references only if they are explicitly listed as direct replacements in official Analog Devices substitution guides.
