Description
The ON Semiconductor UC3843BNG is a pulse width modulation (PWM) controller that operates at a fixed frequency of up to 500 kHz. This device is designed to provide accurate control of power in switching applications, such as DC-to-DC converters, AC-to-DC power supplies, and switched-mode power supplies. Its operation is based on a voltage feedback loop that compares the output voltage with a reference voltage, then adjusts the duty cycle of the PWM signal to regulate the output voltage.
The UC3843BNG features a maximum duty cycle of 50%, which ensures safe operation and prevents the output voltage from exceeding the input voltage. It also includes overvoltage and overcurrent protection to prevent damage to the device or surrounding components. This controller is available in a standard 8-pin DIP (dual in-line package) and SOIC (small outline integrated circuit) packages, making it a versatile solution for power control applications in a variety of industries
