Supertex (Sunnyvale, CA) introduced the HV9805, an LED driver IC, where the LED light source is arranged as a high-voltage LED string in order to accommodate certain lamp form factors, while allowing for cost savings through less complicated cooling and optical arrangements. The driver includes a linear post regulator to provide a pure DC current drive, for flicker free light output. The linear post regulator also provides protection from line voltage transients. Features include:
- Boundary conduction mode, with the output regulated for lowest overhead voltage at the linear regulator.
- Curent rating of 1A.
- A lead(Pb)-free/RoHS compliant 10-lead MSOP package (HV9805MG-G).
