Description

The UC2842BN, part of the UC284xB family of products, is a high-performance current mode PWM controller manufactured by STMicroelectronics. It is a versatile device designed to implement efficient and reliable solutions in various power conversion applications, including switched-mode power supplies (SMPS), DC-DC converters, and battery chargers.

Key Features

  • Adjustable Output: The UC2842BN offers an adjustable output that can be tuned from 5V to a maximum of 30V, providing flexibility to match the requirements of different circuits and applications.
  • High-Frequency Operation: With an operating frequency range up to 500 kHz, this component allows for smaller-sized components, reducing the overall footprint and cost of the power supply design.
  • Current Mode Control: The current mode architecture provides improved transient response, simplified loop compensation, and inherent protection against overcurrent conditions.
  • Low Startup Current: The device's low startup current of less than 1 mA makes it an energy-efficient choice for battery-operated devices and standby power modes.
  • Trimmed Oscillator Discharge Current: Ensures consistent and precise dead time and maximum duty cycle across different units and varying conditions.

Applications

The UC2842BN is suitable for a wide range of applications due to its robust feature set. These applications include but are not limited to:

  • Offline and DC-to-DC power supplies
  • Power converters for computers and telecommunications
  • Industrial power systems
