SA3525SC
SA3525SC 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-𝓀pull output, which increases the driving ability; 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.

built in 5.1 V ± 1.0% reference voltage source
the operating frequency of the on-chip oscillator is 100 Hz ~ 400 kHz
has the function of external synchronization of oscillator
dead time adjustable
the last stage adopts push-pull circuit, and the maximum current can reach 400mA
undervoltage lockout circuit
built in soft start circuit
built in PWM (pulse width modulation)
