The EL7581 is a 3-channel DC-DC converter IC 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 720mA @12V, 570mA @ 15V from 5V input. 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 EL7581 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 EL7581 is available in a 20-pin HTSSOP package and is specified for operation over the full -40oC to +85oC temperature range.
