About the Product

UC2842B Current Mode Controller for Offline and DC-DC Power Converters

The UC2842B is a high-performance current mode controller designed for offline and DC-DC converter applications requiring precise control, high efficiency, and robust protection features. This controller IC is commonly used in professional power supply designs including Antminer APW9, APW12, and Avalon PSU repair scenarios.

With its trimmed oscillator for accurate timing, temperature-compensated reference, and high-gain error amplifier, the UC2842B ensures stable operation across wide environmental conditions and supports high-efficiency switching performance in demanding power conversion architectures.

Key Features & Advantages

  • Precise duty cycle control through trimmed oscillator
  • Temperature-compensated reference for stability
  • High-gain error amplifier for efficient voltage regulation
  • Integrated current sense comparator for fast cycle-by-cycle limiting
  • High-speed MOSFET driver output
  • UVLO on input and reference
  • Programmable output deadtime
  • Latch functions for single-pulse metering
