MXHV9910B

Overview

The MXHV9910B is an off-line high brightness LED driver IC manufactured using a high-voltage BCDMOS on SOI process. It operates with an input voltage range of 8V to 450V and features a buck topology. The device supports PWM dimming and delivers regulated LED drive current for multiple LEDs in series or parallel configurations. It functions within a temperature range of -40°C to +85°C, utilizes a SOIC-8 package, and achieves greater than 90% efficiency at a switching frequency of 64 kHz.

Feature Summary

Integrates internal circuitry for high-brightness LED driving via high-voltage BCDMOS on SOI technology
Supports PWM TTL signal dimming through the PWMD pin interface
Provides regulated output current for flexible LED string arrangements

Applications

Off-line LED lighting systems
High brightness LED driver circuits
LED arrays requiring series and parallel configurations

Procurement Notes

Verify the manufacturer designation as Littelfuse Inc., which acquired IXYS Integrated Circuits. Confirm the specific suffix 'B' against official datasheets to ensure correct revision matching. Check RoHS compliance status directly from the latest documentation. Ensure the SOIC-8 package type aligns with your PCB design requirements before finalizing procurement orders.

Selection Notes

Select this component for applications requiring wide input voltage ranges up to 450V. Consider the 64 kHz operating frequency for EMI management. Evaluate the SOIC-8 package constraints for thermal performance. Verify that the single-output buck topology meets the specific LED load requirements without additional complex circuitry.

Part Context

The MXHV9910 belongs to the MXHV9910 series of high-voltage LED driver ICs. Originally developed by IXYS, the product line is now managed under Littelfuse. These drivers are designed for cost-effective, high-efficiency lighting solutions utilizing specialized semiconductor processes for robust high-voltage operation.
