1 / 20 page  LM2715 TFT Panel Module General Description 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 Ω internal switch. Capable of generating 8V at 240mA 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 al- lowing for easy filtering and low noise. An external compen- sation pin gives the user flexibility in setting frequency com- pensation, which makes possible the use of small, low ESR ceramic capacitors at the output. The LM2715 uses a pat- ented 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 controllable PMOS switch used for controlling the row driver voltages. The switch can be controlled externally with a control pin and delay 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 solu- tion.
