Product Description

-Data Sheet


* General Description 
 

SDH697XS is designed for non-isolated LED driving with floation buck structure,built-in HV MOSFET and depletion mode MOSFET are available.With this structure,inductor current is sensed and closed-loop is formed with the internal error amplifier for high constant current accuracy and high input/output regulation rate.Also,high PF in full range for decreasing switching loss and improving the conversion efficiency.

Furthermore,SDH697XS has a built-in VCC regulator and a high-voltage power supply controller,which is able to supply power to VCC capacitor iin a certain VCC range without any peripheral power supply or HV startup circuit,saving the system cost and volume.

SDH697XS integrated various protections,such as output open circuit protection ,output short circuit protection,cycle-by-cycle over current protection,and over temperature protection. The start-up current and operating current are low and highlight LED can be driven with high efficiency in full range(85VAC-265VAC).
