TPS65150PWPRG4

Power Management - Specialized Overview

The TPS65150PWPRG4 is a universal, compact LCD bias power supply with an integrated VCOM buffer. It provides three output channels: positive VGH and negative VGL via adjustable charge pumps, and VCOM via a high-current buffer. The device operates on input voltages from 1.8 V to 6 V, supporting 2.5 V, 3.3 V, or 5 V rails. Key features include integrated power-on sequencing for VGH and VGL, a high-voltage switch for VGH isolation, and gate shaping signals controlled by a CTRL input. It monitors outputs for power-good status and includes an adjustable shutdown latch.

Power Management - Specialized Feature Summary

• Integrates dual adjustable charge pump drivers for generating positive VGH and negative VGL bias voltages for TFT backplanes.
• Includes a large current integrated buffer specifically designed to provide stable VCOM voltage for the TFT panel.
• Features built-in power-on sequencing for VGH and VGL outputs, eliminating the need for external timing components.
• Provides an adjustable shutdown latch that monitors output voltages and triggers a lockout if any output falls below its threshold.

Power Management - Specialized Applications

• TFT LCD displays in laptop computers
• Monitor applications utilizing 5 V input voltage rails
• Portable devices powered by 2.5 V or 3.3 V input rails

Power Management - Specialized Procurement Notes

Verify the suffix 'RG4' indicates lead-free packaging and RoHS compliance. Confirm the package type is HTSSOP-24 with specified thermal characteristics. Ensure the order quantity matches the manufacturer's standard reel specifications. Check for moisture sensitivity level requirements during storage and handling. Validate that the component meets the required operating temperature range of -40°C to +85°C.

Power Management - Specialized Selection Notes

Select this component when a single IC solution is needed for complete TFT LCD bias generation. It is suitable for designs requiring integrated sequencing and VCOM buffering without external discrete components. Consider the input voltage range compatibility with the system's main power rail. Evaluate the thermal performance within the HTSSOP-24 package for the specific application load.

Power Management - Specialized Part Context

This part belongs to the TPS65150 series of LCD bias power supplies manufactured by Texas Instruments. It is functionally similar to the TPS65150PWPR but differs in packaging and compliance attributes due to the RG4 suffix. The series is designed to simplify the power design for thin-film transistor liquid crystal displays by consolidating multiple bias functions into one compact device.

Power Management - Specialized Replacement Considerations

The TPS65150PWPR is a direct functional equivalent within the same series. Verify that the non-RG4 version meets environmental compliance requirements if necessary. Other members of the TPS65150 family may offer different pinouts or feature sets; consult the specific datasheet for detailed comparison.
