| SD5106A | SD5106A is a boost constant-current LED driver operating from a DC5V to 40V input, with low ripple and an integrated power MOS. It integrates a fixed-frequency oscillator and frequency-compensation circuit to simplify design. When the input voltage is greater than or equal to 12V, SD5106A can drive 5 to 10 1W LEDs in series. The PWM control loop linearly adjusts duty cycle from 0~90%. It includes overcurrent protection and EN-pin logic-level shutdown; internal compensation reduces external component count. | ||
