TPS612564CYFFR Application Field and Working Principle

Introduction

The TPS612564CYFFR is an integrated DC-DC Switching regulator, developed by the Texas Instruments® Corporation (TI) to provide a power supply solution with a low total component count, reducing the board space and layout time.

Main Features

The TPS612564CYFFR offers a wide range of features, such as:

• Wide Input Voltage Range: 4.5V - 20V
• Output Current up to 6A
• Thermal Shutdown Protection
• Internal MOSFET Switch
• Extremely Low Noise Switching (Quasi-Resonant Mode)
• External Sync MOSFET

Applications

The TPS612564CYFFR is designed for and is suitable for a broad range of applications, such as:

• Intermediate Bus Converters
• USB Power Applications
• Amplifiers up to 6A Output
• Point-of-Load DC-DC Regulators
• Portable Equipment Power Supplies
• Notebook and Netbook Chargers
• LED Lighting

Working Principle

The TPS612564CYFFR operates in two different modes, Pulse Width Modified (PWM) Mode or Quasi-Resonant (QR) Mode.

PWM Mode

In PWM Mode, the regulator performs as a normal voltage regulator, working like a basic switch with a fixed switching frequency. PWM mode works best when the output current is low (up to 1A) and when the input-output voltage differential is small.

Quasi-Resonant Mode

In Quasi-Resonant Mode, the TPS612564CYFFR operates more like an oscillator, with variable frequency operation. The frequency of the oscillation is based on the input-output voltage differential and the output current. This allows the TPS612564CYFFR to reduce the switching noise created when operating at high output current levels (greater than 1A). This mode of operation also allows the regulator to reduce losses while improving efficiency.

Conclusion

The TPS612564CYFFR DC-DC Switching regulator is a power supply solution with a low total component count and extreme efficiency. The wide range of features and its two modes of operation allow the regulator to support a wide range of applications. Furthermore, the regulator is exceptionally quiet when operating in Quasi-Resonant Mode, allowing it to be used in environments where noise is a concern.
