Overview
The LT3479EFE#PBF is a high-performance boost DC/DC converter manufactured by Analog Devices Inc., housed in a 16-lead TSSOP package with an exposed thermal pad. It delivers up to 3A of output current and supports adjustable output voltages reaching 42V. The device operates within an input voltage range of 2.5V to 24V and features a programmable switching frequency spanning from 200kHz to 3.5MHz. Integrated functionalities include soft-start, inrush current protection, and cycle-by-cycle current limiting. It functions reliably across an extended temperature range from -40°C to +85°C.
Feature Summary
- Integrated soft-start and inrush current protection for controlled power-up sequences
- Programmable switching frequency allows optimization for efficiency or component size
- Cycle-by-cycle current limiting protects against short circuits and overloads
Applications
- Battery-powered portable equipment requiring efficient step-up conversion
- Industrial control systems utilizing isolated or non-isolated DC/DC topologies
- Automotive electronics operating on varying battery voltages
Procurement Notes
Verify the specific suffix #PBF confirms lead-free compliance and RoHS standards before procurement. Confirm the 16-TSSOP package availability matches your PCB footprint requirements. Check official Analog Devices documentation for any recent design changes or material declarations that may affect long-term supply chain stability.
Selection Notes
Select this component when a robust boost converter with integrated protection features is required. Ensure the external inductor and capacitor values are calculated to support the desired 3A output current at the chosen switching frequency. Verify that the input voltage source can handle the peak input currents during startup without excessive droop.
Part Context
This part belongs to the LT3479 family of full-featured DC/DC converters designed for applications demanding high efficiency and compact solutions. It complements other Linear Technology products by offering a balance of performance and ease of implementation in space-constrained designs.
Replacement Considerations
LT3479EDE#PBF offers identical electrical specifications but utilizes a DFN-14 package instead of TSSOP. Ensure thermal management strategies are adjusted accordingly due to the different package geometry and heat dissipation characteristics.
