MAX16922AUPD/V+T

Overview

The MAX16922AUPD/V+T is a switching voltage regulator featuring a dual step-down DC/DC converter and an integrated LDO, manufactured by Analog Devices Inc./Maxim Integrated. It operates within an input voltage range of 3.7 V to 28 V and utilizes a buck topology with a fixed switching frequency of 2.2 MHz. The device provides four outputs, including dual adjustable regulators and two LDOs, supporting output currents up to 1.2 A. It is housed in a 20-pin TSSOP-EP package and certified to AEC-Q100 standards for automotive applications, functioning reliably between -40°C and +125°C.

Feature Summary

• Integrates dual synchronous step-down converters with two low-dropout linear regulators for comprehensive power management.
• Features high efficiency synchronous rectification optimized for automotive TFT-LCD biasing requirements.
• Includes internal soft-start control to limit inrush current during startup sequences.

Applications

• Automotive TFT-LCD panel power supply systems
• Vehicle infotainment display driver circuits
• Dashboard instrument cluster power regulation

Procurement Notes

Verify the specific suffix 'V+T' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications and RoHS compliance status. Ensure the ordering part number matches the exact pin configuration and thermal pad requirements for your PCB layout. Cross-reference the component date code and lot traceability if required for automotive quality standards. Confirm availability through authorized distributors as stock levels may vary.

Selection Notes

Select this component when designing automotive displays requiring a compact solution with multiple regulated rails from a single high-voltage source. The dual buck architecture reduces external inductor count compared to discrete solutions. Verify that the maximum input voltage of 28 V aligns with the vehicle's electrical system profile. Ensure the thermal performance of the TSSOP-EP package meets the thermal dissipation needs of the application environment.

Part Context

This part belongs to the MAX16922 family of power management ICs designed specifically for automotive liquid crystal display applications. It consolidates multiple power stages into a single small footprint, replacing complex discrete designs. The series is characterized by its robustness against automotive electrical transients and its ability to drive large capacitive loads typical of LCD panels.

Replacement Considerations

Direct substitutes include other variants within the MAX16922 family such as MAX16922ATPA-V-, MAX16922ATPD/V+T, and MAX16922ATPH/V+T. These alternatives share identical functional specifications but differ in package type (TQFN vs. TSSOP) or reel configuration. Verify pin-to-pin compatibility and thermal characteristics before substitution.
