WD5200 is a highly integrated step-down quasi-resonant
WD5200 is a highly integrated step-down quasi-resonant
LED constant current drive switch.非隔离降压型LED恒流驱动IC
On the same wafer, WD5200 integrates high voltage power
MOSFET and controller. In addition, the chip also integrates a high-voltage start
Circuit and inductor current zero-crossing detection circuit without auxiliary winding,
With this function, the system works in quasi-resonant mode and maximizes
Simplify the design of the system.非隔离降压型LED恒流驱动IC
AH8NR8 integrates complete protection functions to ensure system safety
Reliable operation, such as VDD undervoltage protection function, cycle-by-cycle current limit
Control, overheating protection, LED open circuit and short circuit protection, etc.
