Overview
The HV9930LG-G is a variable frequency PWM controller IC designed for LED lamp drivers using a low-noise boost-buck (Ćuk) topology. It operates with an input voltage range of 8 V to 450 V and supports a maximum output current of 350 mA. The device functions within a temperature range of -40°C to +125°C and utilizes an 8-pin SOIC package.
Feature Summary
- Supports hysteric boost-buck (Ćuk) topology for low-noise operation
- Enables constant current regulation without external loop compensation
- Integrates PWM dimming capability for brightness control
Applications
- LED lighting driver circuits
- Off-line current controlled LED systems
- Constant current white LED driving applications
Procurement Notes
Verify the specific suffix 'LG-G' against the official Microchip datasheet to confirm pinout, thermal characteristics, and RoHS compliance status. Ensure the selected package matches the design requirements for the 8-SOIC form factor. Cross-reference the manufacturer part number with authorized distributors to confirm active production status and availability constraints.
Selection Notes
Select this component when a non-inverting buck-boost solution is required for high-voltage LED strings. The integrated Ćuk topology eliminates the need for external compensation networks, simplifying the design process. Consider the wide input voltage range and operating temperature specifications to ensure compatibility with the target power supply and environmental conditions.
Part Context
This part belongs to the HV9930 family of LED drivers from Microchip Technology. It is distinct from the HV9931, which shares similar topological features but may differ in specific electrical ratings or packaging options. The LG-G suffix denotes the specific tape-and-reel packaging and material composition compliant with industry standards.
Replacement Considerations
The HV9931LG-G is a related variant within the same product family. Verify if the HV9931 meets the specific current or voltage requirements of the application before substitution, as direct pin-to-pin replacement should be confirmed via official cross-reference documentation.
