LM2702 - TFT Panel Module

General Description

The LM2702 is a compact bias solution for TFT displays.

It has a current mode PWM step-up DC/DC converter with a 2A, 0.2Ω internal switch.

Capable of generating 8V at 170mA from a Lithium Ion battery, the LM2702 is ideal for generating bias voltages for large screen LCD panels.

LM2702 TFT Panel Module November 2002 LM2702 TFT Panel Module General Description The LM2702 is a compact bias solution for TFT displays. It has a current mode PWM step-up DC/DC converter with a 2A, 0.2Ω internal switch. Capable of generating 8V at 170mA from a Lithium Ion battery, the LM2702 is ideal for generating bias voltages for large screen LCD panels. The LM2702 operates at a switching frequency of 600kHz 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 LM2702 uses a patented internal circuitry to limit startup inrush current of the boost switching regulator without the use of an external softstart capacitor.
