ADM8839ACPZ

Overview

The ADM8839ACPZ is a specialized charge pump regulator integrated circuit designed for color Thin Film Transistor (TFT) Liquid Crystal Displays. It generates three distinct output voltages required for LCD biasing, including negative and positive rails. The device operates within an input voltage range of 2.7 V to 4.2 V. It features a 20-lead LFCSP package. Key electrical parameters include output voltages such as -15 V and other specified levels for display driving applications.

Feature Summary

• Generates multiple bias voltages for TFT LCD panels using charge pump technology
• Integrated power sequencing and voltage regulation for display drivers
• Designed for low-voltage single-supply operation

Applications

• Color TFT LCD panel biasing
