LN2556 Product Overview:
LN2556 is a simple peripheral circuit with independent intellectual property rights.
VFPWM continuous operation mode, suitable for non-isolated constant current LED driver chips in the 8-100V full voltage range.
The LN2556 operates at 160K. Due to the PWM mode of operation, a smaller value of inductor can be used in the application, which saves space. The LN2556 implements two-function switching by controlling the MODE port. MODE is left in the highlight mode, and the MODE is connected to a low level of 1/2 (50%).
