Description

The UCC38C43DG4 is a high-performance, biCMOS pulse-width modulator (PWM) controller from Texas Instruments, designed to cater to a wide range of power supply applications. This versatile component is perfect for those seeking efficient power management solutions in their electronic designs.

Key Features:

  • BiCMOS Technology: The UCC38C43DG4 is built with advanced biCMOS technology, offering the perfect blend of power consumption and speed, ensuring reliable performance in demanding environments.
  • Wide Operating Frequency Range: With an operating frequency range up to 1MHz, this PWM controller can be used in applications requiring high-frequency power conversion, which can lead to smaller and more efficient designs.
  • Low Start-Up and Operating Current: The device features a low start-up current of typically 100µA and an operating current of typically 2.5mA, making it an energy-efficient solution for power supply systems.
  • Programmable Soft-Start: The UCC38C43DG4 includes a programmable soft-start function that limits inrush current during start-up, improving the reliability and lifespan of the power supply.
  • Current-Mode Control: Current-mode control provides inherent line feed-forward, cycle-by-cycle current limiting, and easier loop compensation compared to voltage-mode control.
  • Under-Voltage Lockout (UVLO): Both line and low-side UVLO circuits ensure that the controller remains off unless there is sufficient supply voltage, preventing malfunction at low voltages.

Applications:

The UCC38C43DG4 is ideal for a range of applications including:

  • Switching power supplies
  • DC-to-DC converters
  • Off-line power supplies
  • AC-to-DC adapters
  • Telecommunication equipment
