LM2711 Datasheet (National Semiconductor)

LM2711, TFT Panel Module

The LM2711 is a compact bias solution for TFT displays.

It has a current mode PWM step-up DC/DC converter with a 1.4A, 0.17Ω internal switch.

Capable of generating 8V at 300mA from a Lithium Ion battery, the LM2711 is ideal for generating bias voltages for large screen LCD panels.

The LM2711 can be
