LM2702 Datasheet (National Semiconductor)

LM2702, TFT Panel Module

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 a
