Introduction

AI Translation

The TPS54560 is a 60V, 5A step-down converter integrating an 83mΩ high-side MOSFET. It features a wide input voltage range of 4.5V to 60V, suitable for various applications powered by unregulated supplies, such as industrial or automotive applications. The device employs peak current mode control and supports a wide adjustable switching frequency range set via an external resistor or external clock signal. Frequency Spread Spectrum (FSS) enables excellent EMI performance for the TPS54560 in automotive applications. With a quiescent current of 120μA in sleep mode and a shutdown current of 3.8μA, the device is well-suited for battery-powered systems. It integrates protection features including cycle-by-cycle current limiting and thermal shutdown, and is available in an 8-pin eSOP package.

The device uses fixed-frequency peak current mode control. The internal clock initiates turn-on of the integrated high-side power MOSFET at the beginning of each cycle, causing the inductor current to rise linearly. When the current through the high-side MOSFET reaches the threshold level set by the compensation voltage at the error amplifier compensation pin, the high-side MOSFET turns off. When the high-side MOSFET turns off, the inductor current freewheels through an external diode until the next clock cycle begins. The integrated error amplifier and external compensation network form a feedback loop that regulates the output voltage to the reference voltage. The error amplifier compares the voltage at the FB pin against an internal reference voltage of 0.8V. An increase in load current reduces the feedback.
