Procurement Notes

Verify the exact suffix and tape/reel or tube packaging configuration before ordering, as availability may vary by region. Confirm RoHS compliance status through official documentation. Check for end-of-life notices or discontinuance alerts from Analog Devices. Ensure the supplier provides genuine parts with traceable lot codes. Validate pinout compatibility if substituting into existing designs.

Selection Notes

Select this component when designing power supplies for TFT-LCD displays requiring integrated boost and inverting converters. Consider the 32-TQFN package size for space-constrained layouts. Evaluate thermal performance under maximum load conditions. Verify input voltage compatibility with system battery or rail specifications. Assess output current requirements against the device capabilities for specific display resolutions.

Part Context

The MAX8795A series belongs to Maxim Integrated's portfolio of specialized power management ICs for display applications. It complements other LCD driver solutions by providing integrated power conversion and signal conditioning. The ETJ+ suffix indicates a lead-free, RoHS-compliant variant in a TQFN package. This part is often used alongside gate drivers and source drivers in complete display subsystems.

Replacement Considerations

Check for direct cross-reference part numbers from Analog Devices. Verify pin-to-pin compatibility with existing PCB footprints. Compare electrical parameters such as switching frequency and output voltage ranges. Ensure thermal characteristics match the original design constraints.
