MXHV9910
General Description
The MXHV9910 is a high-efficiency off-line LED driver.
Manufactured using a dialectically isolated process the
MXHV9910 can operate from 8V to 450V. This highly versatile
input operating voltage enables a broad range of High Brightness
(HB) LED applications. The MXHV9910 drives an external
MOSFET at a fixed oscillator frequency set by an external
resistor. Peak constant current to an LED string is maintained
by modulating the MOSFET GATE signal on and off through the
external current sense resistor connected to the CS input.
Dimming of and LED string is controlled by adjusting the duty
cycle of the PWM input, or applying a control voltage from 0 to
250mV to the LD input.
