It allows efficient operation of driver current up to 1.0A output, and the input range is from 7V to 36V. Moreover, PT6903 controls the internal MOS at a modulated switch frequency up to 1MHz. PT6903 drives a single or multiple series LEDs at a constant-current control method; thus, providing constant current light output and enhance PT6903 has linear and PWM dimming functions. Output current to an LED string can be programmed to any value between its minimum value to its maximum value at the linear dimming control input of PT6903.
