HV9911NG-G

Overview

The HV9911NG-G is a high-voltage DC-DC controller IC designed for driving high-brightness LEDs. It supports SEPIC, buck, and boost topologies with PWM dimming capability. The device operates within a supply voltage range of 9V to 250V and features switching frequencies of 100kHz or 350kHz. It is housed in a 16-SOIC package and functions as a single-output driver without an internal switch.

Feature Summary

Supports multiple converter topologies including SEPIC, buck, and boost configurations
Enables precise LED current regulation via constant frequency current mode control
Integrates hardware PWM dimming functionality for backlight applications

Applications

LED backlighting systems
High brightness LED lighting drivers
General purpose DC-DC converter designs

Procurement Notes

Verify the specific suffix (e.g., M934, M901) against design requirements as these denote packaging variations rather than functional differences. Confirm RoHS compliance status through official Microchip documentation prior to integration. Ensure component availability aligns with project timelines due to potential long lead times associated with specialized PMIC inventory.

Selection Notes

Select this component when designing isolated or non-isolated LED drivers requiring flexible topology support. It is suitable for applications needing wide input voltage ranges up to 250V. Engineers should evaluate thermal performance within the 16-SOIC package constraints and ensure external components match the selected switching frequency option.

Part Context

This part belongs to the Microchip HV9911 series of LED lighting driver ICs. The series provides versatile solutions for high-brightness LED applications. The HV9911 family is characterized by its ability to drive single-switch converters with high accuracy, making it a standard choice for industrial and commercial lighting control circuits.

Replacement Considerations

Parameter-equivalent alternatives include HV9911NG-G-M901 and HV9911NG-G. These variants share identical electrical specifications but differ in packaging media such as tape and reel or cut tape formats.
