Microsemi Corporation's UC3842ADM is a high-performance Current Mode PWM Controller. This versatile controller supports multiple topologies including Boost, Buck, Flyback, and Forward converters, enabling efficient step-up and step-down DC-DC power conversion. It features a precise internal voltage reference and a wide operating supply voltage range from 10V to 30V. The UC3842ADM offers a fixed-frequency operation, configurable up to 500kHz, with a maximum duty cycle of 96%. Its output is designed for driving external power transistors and provides positive, isolation-capable output configurations. The component is housed in an 8-SOIC package for surface mounting, suitable for use in industrial, consumer electronics, and communication systems. The operating temperature range for this device is 0°C to 70°C.
