General Description

The LT®3497 is a dual full function step-up DC/DC converter speciﬁcally designed to drive up to 12 white LEDs (6 white LEDs in series per converter) from a Li-Ion cell.

Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors and expensive factory calibration.

The two independent converters are capable of driving asymmetric LED strings.

Key Features

Drives Up to 12 White LEDs (6 in Series per Converter) from a 3V Supply.
Two Independent Boost Converters Capable of Driving Asymmetric LED Strings.
Independent Dimming and Shutdown Control of the Two LED Strings.
High Side Sense Allows “One Wire Current Source” per Converter.
Internal Schottky Diodes.
Open LED Protection (32V).
2.3MHz Switching Frequency.
±5% Reference Accuracy.
VIN Range: 2.5V to 10V.
Dual Wide 250:1 True Color PWMTM Dimming.
