HV9805  
High Voltage  
LED Driver  
General Description  
The HV9805 driver IC is targeted at driving high voltage LED  
strings from mains. High voltage LED strings offer an inherent cost  
advantage with respect to cooling and optics. A boundary mode boost  
converter provides operating voltage to the LED strings and a linear  
post regulator. The linear regulator is arranged as a constant current  
regulator and protects the LED strings from mains overvoltage. The  
constant current regulation provides high quality light, free from any  
form of modulation. The IC is specifically designed for single line  
voltage operation, as opposed to universal AC.  
Features  
► BCM boost PFC  
■
High power factor, > 99%  
► Linear post regulator  
■
Provides true DC LED current  
■
Protects LED load  
► High overall efficiency, > 90%  
► Simple inductor construction  
Applications  
► LED Lamps  
► LED Fixtures  
The boost converter employs a cascode switch for high speed  
switching and convenient generation of the housekeeping (VDD  
)
supply. The low voltage device of the cascode switch is integral to  
the HV9805 and is rated at a current of 1A. VDD power is derived  
with high efficiency and without the need for extra components or  
magnetic windings.
