The LM2715 is a compact bias solution for TFT displays. It has a current mode PWM step-up DC/DC converter with a 1.3A, 0.18 internal switch. Capable of generating 8V at 24 mA from a Lithium Ion battery, the LM2715 is ideal for generating bias voltages for large screen LCD panels. The LM2715 operates at a switching frequency of 1.25MHz allowing for easy filtering and low noise. An external compensation pin gives the user flexibility in setting frequency compensation, which makes possible the use of small, low ESR ceramic capacitors at the output. The LM2715 uses a patented internal circuitry to limit startup inrush current of the boost switching regulator without the use of an external  softstart capacitor. The LM2715 has an internal controllablePMOS switch used for controlling the row driver voltages.  The switch can be controlled externally with a control pin anddelay time. The LM2715 contains a Vcom amplifier and a Gamma buffer capable of supplying 50mA source and sink. The TSSOP-16 package ensures a low profile overall solution.
