LC3300 Variable Frequency Step-up DC/DC Converter

LC3300 Description

LC3300 - Max.3MHz, Variable Frequency Step-up DC/DC Converter .
The LC3300 variable frequency step-up Converter drives white LEDs with a constant current to provide backlight in cell phones, PDAs, and other hand-he.

LC3300 Features

* allowing series connection of the white LEDs so that the LED currents are identical for uniform brightness. An enable input can be pulsed repeatedly to adjust LEDs brightness. The fast 3MHz operation frequency allows for smaller capacitor and inductor. Fault condition protection uses cycle-by cycle

LC3300 Applications
