ADD8754DACPZ-REEL7

Special Purpose Regulators Overview

The ADD8754DACPZ-REEL7 is a specialized integrated circuit designed for TFT LCD panel power, VCOM, and gate modulation applications. It integrates a high-frequency step-up DC-to-DC switching regulator with a 2 A power switch, a logic voltage regulator, a VCOM amplifier, and gate pulse modulation circuitry on a single chip. The device operates with an input voltage range of 3 V to 5.5 V and features selectable output voltages for the logic regulator at 2.5 V, 2.85 V, or 3.3 V. It utilizes a 24-lead LFCSP package.

• TFT LCD panels for notebooks

Special Purpose Regulators Procurement Notes

Verify the specific suffix REEL7 against official Analog Devices documentation to confirm reel packaging specifications. Ensure compatibility with required external charge pump components as the device relies on them for operation. Confirm thermal management requirements due to the integrated 2 A power switch. Validate that the 24-lead LFCSP footprint matches the target PCB design constraints.

Special Purpose Regulators Selection Notes

Select this component when designing power systems for TFT LCD displays requiring integrated regulation and modulation. Consider the need for external charge pump capacitors and inductors. Evaluate the 650 kHz or 1.2 MHz switching frequency options against EMI constraints. Verify that the 3 V to 5.5 V input range aligns with the system's power supply architecture.

Special Purpose Regulators Part Context

The ADD8754 belongs to Analog Devices' portfolio of display driver support ICs. It consolidates multiple functions typically handled by discrete components into a single solution. This integration reduces board space and simplifies the design process for LCD panel power supplies. The device is distinct from general-purpose regulators due to its specialized gate modulation and VCOM capabilities.
