Overview

Product Details

LCD Bias (+5V, -7.5V, +12.5V) Plus 8 LED Power Supply

The LTC3524 is an integrated BIAS and white LED power converter solution for small/medium-sized polysilicon thin film transistor (TFT) liquid crystal (LCD) display panels. A 1.5MHz synchronous boost converter generates a programmable low noise, high efficiency 25mA TFT supply of up to 6.0V. Regulated, low ripple charge pumps are used to generate up to +20V and –20V at 2mA. A second 1.5MHz boost converter powers one or two LED strings with up to five series elements each.
