The UC3842N is a Switched-Mode Power Supply Controller from STMicroelectronics, designed for current-mode type power supplies. It features pulse width modulation (PWM) control, voltage mode control, and adjustable frequency up to 1 MHz. This controller has various protection mechanisms, including soft start, under-voltage lockout, over-voltage protection, and error amplifier for closed-loop control. The UC3842N is suitable for a range of applications, including switch-mode power supplies (SMPS), battery chargers, and LED drivers. It regulates voltage and controls the duty cycle of a power converter, making it suitable for various low to medium power applications in electronics. With its low start-up current and internal oscillator with externally adjustable frequency, this controller provides reliable performance and flexibility in design.
According to the product information, the features of the UC3842N are:
These features make the UC3842N suitable for various power supply applications, such as switch-mode power supplies (SMPS), battery chargers, and LED drivers.
