The UC3842 from STMicroelectronics is a high-performance current-mode PWM controller designed for offline applications. It features a wide input voltage range from 12V to 25V, with a nominal input voltage of 15V. The controller provides a stable output voltage of 5.1V and can deliver up to 1A of output current. Its switching frequency is nominally 250kHz, with a maximum frequency of 275kHz.
This device operates with UVLO thresholds of 16V (on) and 10V (off), making it suitable for various power supply designs. It can achieve duty cycles approaching 100%. The UC3842 has a rise time of 50ns and a maximum supply current of 30mA. The operating temperature range is from 0°C to 70°C.
The UC3842 is available in a surface-mount SOP package. Its specifications make it a versatile component for power management in various electronic systems.
