SY8710 - Buck-Boost 2A LED Lighting Driver


  • Wide input range: 3-30 V
  • 1 MHz switching frequency
  • Very low RDS(ON): 200mΩ
  • Enable and dimming control available
  • RoHS Compliant and Halogen Free
  • Compact package: SOT23-6

Typical Application


SY8710 is a high efficiency buck-boost regulator optimized for driving high power white LED from up to 30V input. It integrates the low RDS(ON) MOSFET and internal compensation. The 1MHz switching frequency allows the use of very small inductor. This, along with the small SOT23-6 package, achieves an extremely small LED driver design.
