LM2715

TFT Panel Module

General Description

Features

n 1.3A, 0.18Ω, internal power switch

n V_INoperating range: 2.2V to 12V

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, 0.18Ω 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 or LLP-24 packages ensure a low profile

overall solution.
