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.
