uc3525 pwm controller
Using the uc3525 PWM Controller - Explanation and Example: Circuit Diagram / Schematic of Push-Pull Converter PWM is used in all sorts of power control and converter circuits. Some common examples , DC-DC converters. UC3525 is used extensively in DC-DC converters, DC-AC inverters,UPS systems, solar inverters, power supplies, battery chargers . you can soon start using UC3525 yourself in such applications . Before going on to the description and application, let’s first take a look at the block diagram and the pin layout. pin configuration Pins 1 (Inverting Input) and 2 (Non Inverting Input) are the inputs to the on-board error amplifier. If you are wondering what that is, you can think of it as a comparator that controls the increase or decrease of the duty cycle for the “feedback” that you associate with Pulse Width Modulation (PWM). This functions either to increase or decrease the duty cycle depending on the voltage levels on the Inverting and Non-Inver...
