  • RoHS Compliant and Halogen Free
  • Compact package: SOT23-5

Typical Application


SY8006 is a high-efficiency 1.5MHz synchronous step-down LED driver capable of delivering 1.2A output current. SY8006 operates over a wide input voltage range from 2.6V to 5.5V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction losses. It also features a 100mV feedback voltage for high efficiency operation.
