3-Channel DC/DC Converter Evaluation Board

Overview

The EL7583 is a 3-channel DC/DC converter IC that is designed primarily for use in TFT-LCD applications. It features a PWM boost converter with 2.7V to 14V input capability and 5V to 17V output, which powers the column drivers and provides up to 470mA at 12V, 370mA at 15V from a 5V supply. A pair of charge pump control circuits provides regulated outputs of VON and VOFF supplies at 8V to 40V and -5V to -40V, respectively, each at up to 60mA.
