PWM Module with Dual Source/Sink Outputs using SG3525
SG3525 PWM module is a great tool for every hobbyist. This circuit can be used in various applications such as switching power supply, DC-DC converter, DC motor speed controller, LED dimer, High voltage power supply, solenoid driver, and electronic DC load. This low-cost pulse width modulator control circuit offers improved performance. The circuit has various options such as adjustable PWM, adjustable frequency, optional soft start, dual source/sink output with 50% duty cycle, single output with 0 to 100% duty cycle and output signal voltage level TTL-5V or 12V selection using a jumper. The 5V PWM signal is rated at low current hence don’t draw more than 20mA. The 12V outputs are capable to drive a MOSFET directly.
