Product Overview: UCC28086PW from Texas Instruments

The UCC28086PW is a versatile, dual-output, non-synchronous PWM controller designed by Texas Instruments to deliver precision power regulation in a variety of applications. This advanced controller is specifically engineered to facilitate efficient power conversion in systems requiring a compact, high-performance solution.

Key Features

• Push-Pull Architecture: The UCC28086PW implements a push-pull control scheme which significantly enhances the efficiency of the power conversion process, making it ideal for applications that demand high power density and low heat dissipation.
• Wide Supply Voltage Range: With an operational voltage range from 8V to 14V, this PWM controller is highly adaptable and can be integrated into a broad spectrum of power systems.
• Programmable Dead-Time: The ability to program dead-time (the period when both outputs are inactive) allows for fine-tuning of the power stage to optimize performance and minimize cross-conduction losses.
• High-Frequency Operation: The UCC28086PW can operate at frequencies up to 1MHz, enabling the use of smaller, more efficient transformers and filters, thus reducing the overall size and cost of the power supply.
• Internal Soft-Start: An integrated soft-start function limits inrush current during startup, enhancing system reliability and extending the lifespan of the power supply components.

Applications

The UCC28086PW's robust feature set makes it suitable for a wide array of applications, including:

• DC-DC Converters
• Isolated Power Supplies
• Telecommunication Equipment
• Industrial Systems
• Uninterruptible Power Supplies (UPS)
