The EL7581 is a 3-channel DC/DC converter IC which isdesigned primarily for use in TFT/LCD applicaTIons. Itfeatures a PWM boost converter with 2.7V to 14V inputcapability and 5V to 17V output, which powers the columndrivers and provides up to 720mA @12V, 570mA @ 15Vfrom 5V input. A pair of charge pump control circuits provideregulated outputs of VON and VOFF supplies at 8V to 40Vand -5V to -40V, respecTIvely, each at up to 60mA.The EL7581 features adjustable switching frequency,adjustable soft start, and a separate output VON enablecontrol to allow selecTIon of supply start-up sequence. Anover-temperature feature is provided to allow the IC to beautomaTIcally protected from excessive power dissipation.The EL7581 is available in a 20 Ld HTSSOP package and isspecified for operation over the full -40°C to +85°Ctemperature range.
