A9910
AC-DC LED DRIVER UNIVERSAL HIGH BRIGHTNESS LED DRIVER
DESCRIPTION
FEATURES
The A9910 is a PWM high-efficiency LED driver >90% efficiency
control IC. It allows efficient operation of 10V to 600V input range
high-brightness (HB) LEDs from voltage sources Constant-current LED driver
ranging from 10VDC up to 600VDC. The A9910 Applications from a few mA to more than 1A
controls an external MOSFET at fixed switching
output
frequencies up to 300kHz. The frequency can be LED string from one to hundreds of diodes
programmed using a single resistor.
