APS54083 can achieve dimming and PWM dimming linear, lines
of barefoot adjusting the effective voltage range 0.1-0.7V.PWM dimming frequency range
around 100HZ-30KHZ.
Dimming high luminance of 65,536 (256 * 256) high-level brightness dimming.
APS54083 is a PWM mode of operation, high efficiency, the outer
circumference simple external power MOS for 5-80V input
precision drop pressure constant current LED driver chips. Maximum output power 150W,
the maximum current of 6A.
APS54083 operating frequency can be programmed by external resistors
to set, while the internal frequency jitter circuit, other devices can be reduced
EMI interference. Further uses peak current mode sampling can improve the
current accuracy under a wide input voltage.
APS54083 with an output short circuit protection, 5V ~ 80V
under input conditions, without damaging the short short-circuit power devices.
There APS54083 current over temperature regulation. When the chip
temperature inside reached about 135 ℃, it will automatically reduce the output
flow
