Frequently Asked Questions
What input voltage range can the HV9931P-G handle for off-line LED driving?
The HV9931P-G is designed for off-line operation and can support input voltages up to approximately 500 V, making it compatible with universal AC mains inputs ranging from 85 V to 265 V AC. This wide range allows designers to use a single design for global markets without switching components.
How does the HV9931P-G regulate LED current in a lighting driver circuit?
The HV9931P-G uses cycle-by-cycle current-mode control to regulate the average LED current. The controller senses the peak inductor current through an external sense resistor and adjusts the MOSFET on-time to maintain constant LED current output, typically within ±5% accuracy across line and load variations.
Which LED lighting applications are best matched to the HV9931P-G in the DIP-8 package?
The HV9931P-G in the 8-pin DIP package is ideal for compact LED driver boards used in LED bulb replacements, LED tube fixtures, and low-power commercial luminaires up to approximately 25 W. Its through-hole DIP-8 footprint simplifies prototyping and low-volume production while the integrated gate driver reduces the total external component count to fewer than 10 parts.
