UC3824DW High-Speed PWM Controller IC

UC3824DW High-Speed PWM Controller IC

The UC3824DW is a high-speed, low-power Pulse Width Modulation (PWM) controller designed by Texas Instruments. It is primarily used in DC-DC converters, power supplies, and motor control applications. The IC integrates advanced control features such as current mode control, under-voltage lockout (UVLO), and over-current protection, which enhance its performance and reliability in power conversion systems. The device is packaged in a surface-mount SOIC-16 (DW) package, allowing it to be used in compact designs.

If you are in Nashik you can buy this Electronic Component at our local shop at New CBS, Nashik or you can place order online and get it delivered at your doorstep anywhere in India.

Features of UC3824DW High-Speed PWM Controller IC

  • Current-Mode Control: Allows precise regulation of output current, improving performance in power supply and motor control systems.
  • Programmable Oscillator Frequency: Frequency can be set via external resistors and capacitors, supporting a wide range of operational requirements.
  • Under-Voltage Lockout (UVLO): Prevents the controller from operating when the supply voltage is below a safe level, ensuring reliable startup.
  • Soft Start: Limits the inrush current at startup, reducing stress on power components and increasing system reliability.
  • Wide Supply Voltage Range: Operates over a wide input voltage range (8V to 30V), supporting various power designs.
  • Fast PWM Operation: Supports high-speed switching, making it suitable for high-frequency DC-DC conversion applications.

Specifications of UC3824DW High-Speed PWM Controller IC

  • Supply Voltage: 8V to 30V
  • Output Current: 1A (typical drive capability)
  • Oscillator Frequency: Programmable up to 1 MHz
  • PWM Frequency: 500 kHz (max)
  • UVLO Threshold: 7.6V (turn-on), 7.4V (turn-off)
