概述
LP6291H is a single channel, low power, high voltage, high current, VCOM and half AVDD buffer. The device operates on supplies from 4.5V to 19.5V with 3.0mA typical quiescent current.
LP6291H also provides common mode input ability beyond the supply rails and rail-to-rail output capability to provide maximum dynamic range for the specified operating voltage range.
LP6291H features high output drive capability of 1.3A peak AC current (typical, sink and source), 50V/us slew rate, and 35MHz bandwidth to quickly settle outputs for 120Hz frame rate and full HD resolution. In addition, LP6291H provides Over Temperature Protection (OTP), Over Current Protection (OCP), and Output Short Circuit Protection functions (SCP), which provide maximum system protection for demanding TFT-LCD panel applications.
