The UC2843B with SOP-8 DC-DC Controllers ROHS is a high-performance monolithic integrated circuit designed for use in a wide variety of DC-DC regulator applications. It is manufactured by Youtai, a leading manufacturer of semiconductor components. This device features an enhanced BiCMOS design, resulting in improved transient response, efficiency, regulation, and power dissipation. It offers adjustable ouput voltage, temperature compensated current limiting, TTL-compatible shutdown control, synchronous rectifiers, and short circuit protection. An internal oscillator operates the pulse width modulation (PWM) for excellent loop stability. This device offers current-mode control with internal slope and peak current compensation, allowing operation over a wide input voltage range. Its wide bandwidth also allows constant frequency operation over a wide range of load conditions. This device is designed to meet the requirements of industrial and commercial applications.
