UC3842BD1013TR Product Details

Product Description:

The UC3842BD1013TR is a surface-mount, switching controller IC from STMicroelectronics, designed for use in DC-DC converters, particularly in step-up and step-up/step-down applications. This IC is based on the UC3842 base part number and features a current-mode control technique with pulse-width modulation (PWM) for efficient and reliable voltage regulation.

Features:

  • Frequency Control: The IC operates at a frequency of up to 500 kHz, allowing for high-frequency switching and efficient power conversion.
  • Current-Mode Control: The IC uses current-mode control, which provides better regulation and stability compared to voltage-mode control.
  • Pulse-Width Modulation: The IC uses PWM to regulate the output voltage, ensuring a high level of precision and accuracy.
  • High Efficiency: The IC is designed for high-efficiency operation, with a maximum duty cycle of 100% and a maximum supply current of 17mA.
  • Wide Operating Range: The IC operates over a wide temperature range of 0°C to 70°C and can handle input voltages from 10V to 30V.

Applications:

  • Primary Applications: The UC3842BD1013TR is suitable for use in DC-DC converters, particularly in applications where high-frequency switching is required, such as in power supplies, motor drives, and other high-power applications.
  • Secondary Applications: The IC can also be used in other applications where a high-frequency switching controller is needed, such as in audio amplifiers, LED drivers, and other high-frequency power conversion applications.

Alternative Parts:

  • UC3842BD1013TR: This is the base part number for the UC3842BD1013TR, which is a surface-mount version of the IC.
  • UC3842BD1013R: This is a through-hole version of the IC, which is suitable for use in applications where a through-hole package is required.

Embedded Modules:

  • DC-DC Converters: The UC3842BD1013TR is often used in DC-DC converters, particularly in applications where high-frequency switching is required.
  • Power Supplies: The IC is also used in power supplies, such as in switch-mode power supplies and other high-power applications.
