.The UTC3843E with Switching Controllers SOP-8 RoHS manufactured by Youwang Electronics is a Proportional-Integral (PI) Voltage Mode Controller. It features an improved platform that provides enhanced efficiency over conventional controllers. This switching controller is designed to improve system power density, reduce the size of resistor power stages, and produce lower acoustic noise than traditional designs. The UTC3843E has an integrated low-ripple fixed frequency current-mode (CCM) controller, plus a voltage mode PFC control loop with auto-skip function. The SOP-8 package also includes thermal protection (TP), over current protection (OCP) and short circuit protection (SCP). RoHS certified, it is suited for DC-DC converters and low-power SMPS applications.
