Introducing the UCC28220 PWM Controller from Texas Instruments

The UCC28220 from Texas Instruments is a highly sophisticated, dual interleaved Pulse Width Modulation (PWM) controller designed to cater to a variety of power supply applications. This innovative component is engineered to provide maximum efficiency and reliability for systems requiring a robust power management solution. The UCC28220 is an ideal choice for applications such as servers, telecommunications, data communications, and industrial systems where efficient power conversion is critical.

Key Features

• Interleaved Dual-Channel Operation: The UCC28220 features two PWM channels that operate 180 degrees out of phase, which significantly reduces input and output ripple currents. This results in smaller and less expensive filtering components, improved efficiency, and reduced electromagnetic interference (EMI).
• Advanced Control Methodology: It utilizes peak current mode control for immediate response to load changes and inherent cycle-by-cycle current limiting for enhanced protection.
• Wide Range of Operating Frequencies: The device supports a broad range of switching frequencies from 50 kHz to 1 MHz, allowing designers to optimize their power supply for size, efficiency, and performance.
• Programmable Soft-Start: To mitigate inrush current during startup, the UCC28220 offers a programmable soft-start feature that gradually ramps up the output voltage, thereby enhancing system reliability.
• Integrated Gate Drivers: The controller includes high-current totem-pole outputs for direct driving of power MOSFETs or IGBTs, simplifying the design and reducing external component count.

Efficiency and Protection

The UCC28220 is designed with energy efficiency in mind. It features low startup current and a quiescent current of only 1.3 mA per channel during operation. Additionally, it incorporates a range of protection features such as overvoltage, undervoltage lockout, and programmable overcurrent protection, ensuring the longevity and safety of the power supply and the end application.

Easy Integration

With its compact form factor and comprehensive feature set, the UCC28220 is easy to integrate into new and existing designs. Its versatility and performance make it a go-to choice for engineers looking to create efficient, high-performance power systems with a reduced footprint.
