Step-Up Regulator, Internal Charge Pumps, Switch Control, and Operational Amplifier for TFT LCDs
MAX8784
General Description
The MAX8784 generates supply rails for the thin-film transistor (TFT) liquid-crystal display (LCD) panels in TVs and monitors. It includes a step-up regulator, a regulated positive and a negative charge-pump, three high-current operational amplifiers, and Dual Mode™, logic-controlled, high-voltage switch control block. HVS mode automatically increases the output voltages of the boost regulator and the positive charge-pump to stress test display panels during production. The MAX8784 can operate from input voltages of 4V to 5.5V and is optimized for LCD TV panel and LCD monitor applications.
