STMicroelectronics E-UC3842BN is a high-performance current-mode PWM controller designed for isolated and non-isolated power supply architectures. This versatile device supports boost, flyback, and buck-boost topologies, enabling efficient step-up and step-down voltage conversion. With an operating temperature range of 0°C to 70°C, it is well-suited for applications in industrial automation, consumer electronics, and lighting control. The E-UC3842BN features a maximum duty cycle of 96% and offers flexible frequency control up to 500kHz. Its output configuration is positive and isolation capable, with a single output phase driving a transistor. The IC is housed in an 8-Mini DIP package, facilitating through-hole mounting. This controller operates from a supply voltage of 10V to 30V.
