NON-ISOLATED BUCK LED LIGHTING DRIVE IC WITH LOW POWER ANG HIGH
CONSTANT CURRENT ACCURACY
SD670XS is designed for non-isolated LED driving with floating Buck
structure, and high constant current accuracy and high linear/load
regulation available with assistant of special sense technology.
SD670XS integrates various protections, such as output open circuit
protection, cycle-by-cycle current limit protection and over temperature
The start-up current and operating current are low and highlight LED can
be driven with high efficiency in full range (85VAC~265VAC).
SD670XS integrates high voltage power MOSFET, reducing the system
cost and the whole volume.
Built-in 500V high voltage power MOSFET
Constant current with high accuracy for LED (<±3%)
Output open circuit protection
CS open circuit protection
VCC undervoltage protection
Over temperature protection
Cycle-by-cycle current protection
No auxiliary winding
T5/T8 LED Lamp
