Overview
The LT3494AEDDB#TRPBF is a boost switching regulator IC manufactured by Analog Devices Inc. It operates with an input voltage range of 2.3V to 16V and provides a single adjustable output voltage up to 40V. The device delivers a switch current of 225mA and features a low quiescent current of 65µA. It utilizes an 8-lead DFN package with exposed pad, suitable for surface mount applications across a temperature range of -40°C to +85°C.
Feature Summary
- Integrated synchronous boost converter topology for high efficiency
- Adjustable switching frequency allows optimization for size and performance
- Low quiescent current enables extended battery life in portable designs
- Compact 8-lead DFN package facilitates space-constrained layouts
Applications
- Battery-powered portable electronics requiring step-up conversion
- Single-cell lithium-ion or alkaline battery charging systems
- LED driver circuits utilizing boost topologies
- General-purpose DC-DC power supply modules
Procurement Notes
Verify the exact suffix TRPBF indicates tape and reel packaging when ordering. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the order matches the specific A-grade variant requirements for electrical characteristics. Cross-reference the manufacturer part number with authorized distributor catalogs to prevent counterfeit components.
Selection Notes
Select this component when an input voltage below the required output level must be boosted efficiently. The 225mA switch current limits suitability for high-power loads; verify load requirements against this limit. The adjustable frequency feature permits trade-offs between external component size and electromagnetic interference. Ensure the selected inductor supports the peak current demands of the internal switch.
Part Context
This part belongs to the LT3494 family of boost regulators from Analog Devices. It shares architectural similarities with other members like the LT3494EDDB but differs in specific electrical tolerances and grading. The family targets low-power, battery-operated applications where efficiency and small footprint are critical design constraints.
Replacement Considerations
LT3494EDDB#TRPBF is a related variant within the same product family. Verify pin compatibility and electrical parameter differences before substitution. Consult official documentation for any changes in thermal performance or switching characteristics between variants.
