MAX9550EZK+T

Video Amps And Modules Overview

The MAX9550EZK+T is a high-current VCOM drive buffer designed for TFT LCD applications. It operates on a single supply voltage ranging from 7V to 20V, with a typical quiescent current of 4mA per channel. The device provides an output settling time of less than 2µs to within 0.1% of the output voltage. It features a peak transient output current capability of up to 830mA and a continuous output current of 55mA under specified conditions. The input offset voltage is typically 1mV, with a common-mode rejection ratio of 96dB. The component is housed in a 5-pin Thin SOT-23 package and is rated for operation between -40°C and +85°C.

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix 'EZK' corresponds to the lead-free Thin SOT-23-5 package configuration as listed in the manufacturer's ordering guide. Confirm that the '+T' designation indicates tape-and-reel packaging if required for automated assembly processes. Ensure compatibility with the required supply voltage range and load capacitance specifications before finalizing procurement.

Video Amps And Modules Selection Notes

Select this component when a single-channel VCOM buffer with high transient current capability is required for TFT LCD backplanes. Consider the 5-pin Thin SOT-23 package for space-constrained designs. Evaluate the need for thermal management given the exposed paddle functionality in other packages, though this specific package relies on board-level dissipation. Verify that the 7V to 20V supply range aligns with the system design.

Video Amps And Modules Part Context

This part belongs to the MAX9550/MAX9551/MAX9552 family of high-current VCOM drive buffers. While the MAX9550 offers a single channel, the MAX9551 provides dual channels and the MAX9552 offers four channels. All variants share similar electrical characteristics but differ in pin count and package options, including µMAX and TSSOP configurations.

Video Amps And Modules Replacement Considerations

Direct substitutes include the MAX9551EUA+T (dual channel) or MAX9552EUD+T (quad channel) if additional channels are needed, provided the package footprint can be adapted. Other single-channel alternatives may require verification of pinout compatibility and electrical parameter alignment.
