TPS65150PWP

Power Management - Specialized Overview

The TPS65150PWP is a compact LCD bias power supply IC from Texas Instruments, designed to provide all three required voltages for Thin Film Transistor (TFT) LCD displays. It features an input voltage range of 1.8 V to 6 V, supporting 2.5 V or 3.3 V laptop rails and 5 V monitor rails. The device includes two adjustable charge pump drivers for positive V(GH) and negative V(GL) biases, an integrated high-current buffer for V(COM), and a high-voltage switch for V(GH) isolation. It operates within a temperature range of -40°C to +85°C in a 24-pin HTSSOP package.

Power Management - Specialized Feature Summary

• Integrates dual adjustable charge pumps for generating positive and negative TFT gate bias voltages
• Includes a built-in high-current buffer amplifier specifically for driving the V(COM) line
• Features programmable power-on sequencing for V(GL) and V(GH) without external components
• Provides integrated monitoring with adjustable shutdown latch functionality for output protection

Power Management - Specialized Applications

• TFT-LCD panels in notebook PCs
• Monitor displays utilizing 5 V input rails
• Portable devices powered by 2.5 V or 3.3 V systems

Power Management - Specialized Procurement Notes

Verify the specific suffix 'PWP' corresponds to the tube packaging variant rather than the 'PWPR' tape-and-reel version. Confirm the operating temperature grade matches the application requirements, as industrial variants may differ. Ensure the ordering information aligns with the exact pinout and thermal characteristics specified in the official datasheet to avoid integration errors.

Power Management - Specialized Selection Notes

Select this component when a low-input voltage solution is required for TFT-LCD biasing. It is suitable for applications needing integrated V(COM) buffering and precise voltage sequencing. Consider the HTSSOP-24 package constraints and the 1.8 V to 6 V input range compatibility with the system's main power rail before finalizing the design.

Power Management - Specialized Part Context

This part belongs to the TPS65150 series of LCD bias ICs. It serves as a complete power solution for TFT backplanes, replacing discrete boost converters and linear regulators. The PWP designation indicates a specific tube package configuration within the broader family that also includes reel options and automotive-grade variants like the QPWPR.
