LT3497规格书详情
DESCRIPTION
The LT®3497 is a dual full function step-up DC/DC converter specifi cally 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.
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
■ Requires Only 1µF Output Capacitor per Converter
■ Available in a 3mm × 2mm 10-Pin DFN Package
APPLICATIONS
■ Cellular Phones
■ PDAs, Handheld Computers
■ Digital Cameras
■ MP3 Players
■ GPS Receivers
