Since their introduction in the mid 1980?s, the bipolar UC3842 family of Pulse width modulation (PWM)controllers has grown to become the most widely-used control strategy in the power supply industry. [1] The reasons for success are quite clear, the devices feature an elegantly simple yet very effective control architecture, they use only 8 pins, they can drive MOSFET gates directly and they offer superior performance and protection at an affordable price.
