LV5234VZ-MPB-H

LED Driver IC Overview

The LV5234VZ-MPB-H is a 9-channel LED driver IC manufactured by onsemi. It belongs to the LV5235 series and is designed for LED lighting applications. The device features internal current regulation for each channel, supporting PWM dimming capabilities. It operates within a temperature range of -25°C to 75°C (TA) and utilizes a surface mount package. The component integrates frequency control with an operating frequency of 1MHz.

LED Driver IC Feature Summary

• Integrates nine independent output channels for precise LED current control
• Supports Pulse Width Modulation (PWM) dimming for brightness adjustment
• Features internal circuitry for stable operation without external current-setting resistors

LED Driver IC Applications

• General LED lighting systems
• Solid-state lighting fixtures
• LED backlighting modules

LED Driver IC Procurement Notes

Verify the specific suffix and tape-and-reel packaging configuration against the official datasheet before ordering. Confirm that the intended application environment falls within the specified ambient temperature range of -25°C to 75°C. Ensure compatibility with the required PWM dimming signal levels. Cross-reference the part number with the manufacturer's latest documentation to confirm active status and any potential design changes.

LED Driver IC Selection Notes

Select this component when a multi-channel solution is required for uniform LED driving. It is suitable for designs needing integrated PWM dimming functionality. Consider the thermal performance limits relative to the expected ambient conditions. Evaluate the pin count and package size against the available PCB real estate. Compare against other members of the LV523x family if different channel counts are needed.

LED Driver IC Part Context

This part is part of onsemi's LED driver portfolio, specifically the LV5235 series. It serves as a specialized integrated circuit for managing multiple LED strings in lighting applications. The device simplifies design by combining power switching and control logic into a single package, reducing the component count compared to discrete solutions.

LED Driver IC Replacement Considerations

The LV5232VH-MPB-H is a documented alternative within the same product family, offering 16 channels instead of 9. Verify pinout compatibility and channel count requirements before substitution. Other models in the LV523x series may offer different channel configurations or feature sets.
