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. The LED string Linear and PWM dimming capability
is driven at a constant current rather than a constant Input voltage surge ratings up to 600V
voltage, thus providing a constant light output and an Available in SOP8 Package
enhanced reliability. The output current can be
programmed between a few milliamps and up to
APPLICATION
more than 1.0A. The A9910 uses a rugged
high-voltage junction isolated process that can DC/DC or AC/DC LED driver applications
withstand an input voltage surge up to 600V. The RGB backlighting LED driver
output current to a LED string can be programmed to Backlighting of flat panel displays
any value between zero and its maximum value by General-purpose constant current source
applying an external control voltage at the linear Signage and decorative LED lighting
dimming control input of the A9910. The A9910 Automotive
