UC2844BN Product Details

Product Description:

The STMicroelectronics UC2844BN is a high-performance, 8-pin, 8-DIP (0.300, 7.62mm) packaged, switching controller IC designed for step-up and step-up/step-down DC-DC conversion applications. This current-mode, pulse-width modulation (PWM) controlled IC is ideal for use in a wide range of applications, including power supplies, battery chargers, and other high-frequency switching power supplies.

Features:

  • Frequency Control: The UC2844BN features frequency control, allowing for precise control over the switching frequency.
  • Current-Mode Operation: The IC operates in current-mode, providing high efficiency and low ripple.
  • Pulse Width Modulation (PWM): The IC uses PWM to regulate the output voltage.
  • High Frequency Operation: The IC can operate at frequencies up to 500kHz.
  • Low Power Consumption: The IC has a low operating supply current of 12mA.
  • Wide Input Voltage Range: The IC can operate with an input voltage range of 10V to 30V.

Applications:

  • Primary Applications: The UC2844BN is suitable for use in power supplies, battery chargers, and other high-frequency switching power supplies.
  • Secondary Applications: The IC can also be used in other applications such as LED drivers, motor drives, and other high-frequency switching applications.

Alternative Parts:

  • UC2844: The UC2844 is a similar IC with the same functionality but without the frequency control feature.

Embedded Modules:

  • Power Supplies: The UC2844BN can be used in a variety of power supply applications, including AC-DC and DC-DC converters.
  • Battery Chargers: The IC can be used in battery chargers for charging batteries efficiently and safely.
