The EL7583 is a 3-channel DC/DC converter IC which 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 @ 12V, 370mA @ 15V from 5V supply. A pair of charge pump control circuits provide regulated outputs of VON and VOFF supplies at 8V to 40V and -5V to -40V, respectively, each at up to 60mA. The EL7583 features adjustable switching frequency, adjustable soft start, and a separate output VON enable control to allow selection of supply start-up sequence. An over-temperature feature is provided to allow the IC to be automatically protected from excessive power dissipation. The EL7583 is available in a standard 20 Ld TSSOP package and the Pb-free 20 Ld HTSSOP package. Both are specified for operation over the full -40°C to +85°C temperature range.
