Product Summary

The LTC3206EUF#TRPBF is a highly integrated multidisplay LED controller. The part contains a high efficiency, low noise fractional step-up/direct-connect charge pump to provide power for both main and sub white LED displays plus an RGB color LED display. The LTC3206EUF#TRPBF requires only four small ceramic capacitors plus two resistors to form a complete 3-display LED power supply and current controller. The LTC3206EUF#TRPBF charge pump optimizes efficiency based on VIN and LED forward voltage conditions. It is available in a 24-lead (4mm * 4mm) QFN package. The applications of the LTC3206EUF#TRPBF include Cellular Phones, Wireless PDAs, Multidisplay Handheld Devices.
