HV9801ANG-G

Overview

The HV9801ANG-G is a single-output AC/DC offline switcher designed for LED lighting applications. It utilizes a Buck topology to regulate current with PWM dimming capabilities. The device operates within an input voltage range of 15 V to 450 V and delivers an output current of 165 mA. It features short circuit and thermal protection mechanisms. The component is housed in a 16-SOIC package, supports surface mount installation, and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Integrated PWM dimming control for adjustable brightness
• Built-in short circuit and thermal protection circuits
• Single-channel constant current regulation

Applications

• AC/DC offline LED driver designs
• General solid-state lighting fixtures
• Commercial LED illumination systems

Procurement Notes

Verify the specific suffix 'ANG' confirms the 16-SOIC package and tube packaging format. Confirm RoHS compliance status through official Microchip documentation. Ensure design compatibility with the specified 15 V to 450 V input range and 165 mA output requirement before procurement.

Selection Notes

Select this component for high-voltage offline LED applications requiring buck conversion. It suits designs needing integrated protection against shorts and overheating. The 16-SOIC package facilitates surface mount assembly. Verify that the required operating temperature range aligns with the -40°C to +125°C specification.

Part Context

This part belongs to the Microchip HV9801 series of LED drivers. It is distinct from the HV9801ALG-G, which uses an SOIC-8 package. The HV9801ANG-G provides similar functional capabilities but in a larger footprint suitable for higher power dissipation or different pinout requirements.

Replacement Considerations

The HV9801ALG-G is a related variant with an SOIC-8 package. Direct substitution requires verifying pinout compatibility and thermal management differences due to the package change.
