SA3525SC
SA3525 is a single chip integrated PWM control chip with excellent performance, complete functions and strong universality. It is simple, reliable, convenient and flexible. The output drive is in the form of push-pull output, which increases the driving capacity; It contains undervoltage locking circuit, soft start control circuit and PWM latch. It has overcurrent protection function, adjustable frequency and can limit the maximum duty cycle.
