UC3842BN General Description

The UC3842BN is a pulse width modulation controller that is designed for controlling power supply systems. It operates with a voltage supply range of 7V to 35V and a current of 25mA. This controller is capable of regulating output voltage levels by adjusting the width of the pulses delivered to the power supply.The UC3842BN features a built-in oscillator that can operate at a frequency range of 100Hz to 1MHz, making it suitable for a wide range of power applications. It also includes a soft start function to limit the inrush current when the power supply is turned on. Additionally, the UC3842BN has built-in protection features such as overcurrent protection and thermal shutdown to ensure the safety and reliability of the power supply system. It is available in a 16-pin DIP package, making it easy to integrate into various electronic circuits.
