LTC3490ES8#PBF Description

Short technical summary and product information.

The LTC3490ES8#PBF from Analog Devices is a high-efficiency boost converter designed as a constant current LED driver for 1W LED applications. It delivers 350mA of constant current with up to 4V of compliance, operating from a single cell or two NiMH or alkaline cells.

 

Key electrical specifications include a 1.3MHz fixed switching frequency, low quiescent current of less than 1mA, and very low shutdown current of less than 50µA. The device incorporates synchronous rectification, achieving up to 90% efficiency. It also features dimming control via the CTRL/SHDN pin and an undervoltage lockout to protect batteries.

 

The LTC3490ES8#PBF is available in a low-profile, thermally enhanced 8-lead SOIC package (S8). This surface-mount package is suitable for compact designs.

 

Applications for this LED driver include portable lighting and rechargeable flashlights where efficient and reliable LED current control is essential.
