The trend of simple system and low cost puts higher requirements, such as excellent constant current characteristics and high PF etc., for IC designer.

Among a number of Brazilian bulb applications, MT7608H received a good market feedback due to its high cost-effectiveness and excellent performance. MT7608H is a linear LED driver with low operating voltage, simple peripheral circuit, PF>0.7, 108Vac-265Vac wide input voltage, and single chip can be used in within 10W applications.



 Features 
  • Supports 108Vac-265Vac input, <2% input power differences between 127Vac and 220Vac input

  • PF>0.7

  • Single chip is applied within 10W applications

  • Adopts self-developed innovative technologies

  • Low BOM cost, lowest cost scheme for Brazil bulb
