LC3300 Product details

Description

The LC3300 variable frequency step-up Converter drives white LEDs with a constant current to provide backlight in cell phones, PDAs, and other hand-held devices.

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 current limiting to sense maximum inductor current and over-voltage protection. The 0.2V low reference voltage minimized the power loss across the current sense resistor. The converter can operate fro.
