DC-DC converters are an essential component of many electronic systems. The JRW060A0F is a multi-output non-isolated DC-DC converter capable of supplying a range of higher voltages. It is a fixed-frequency, step-down converter that is regulated for short-circuit protection. This application note provides an overview of the main features and working principles behind the JRW060A0F.

Overview

The JRW060A0F is a multi-output non-isolated DC-DC converter which converts a wide input voltage range to regulated output voltages. It is a fixed-frequency, step-down converter with working input voltages of 4.5V to 24V and a maximum output current of up to 6A (on single output). It also features flexible and robust short circuit protection to help minimize output voltage drops in case of an unexpected overcurrent.

In terms of features, the JRW060A0F is designed to be efficient with multiple output voltages, high-speed transient response, and no switching noise. It is also highly integrated, featuring low-EMI operation, soft start, leading edge modulation, synchronous rectification, current limiting, and over-temperature protection.

One of the unique features of the JRW060A0F is its ability to provide multiple outputs. It can be configured to supply up to five independently regulated outputs that can be configured in parallel, making it an ideal solution for multi-card or distributed power applications.

Working Principle of the JRW060A0F

The JRW060A0F is a non-isolated DC-DC converter, which means that it relies on a shared ground to create an electrical connection between its input and output. It is also a step-down converter, meaning that it reduces the input voltage to generate the desired output voltage. The JRW060A0F is a fixed frequency converter, which means that it operates at a fixed frequency for the entire range of input and output voltages.

The JRW060A0F works by taking the input voltage, which is usually higher than the desired output voltage, and reducing it to the desired output voltage. This is done by passing the input voltage through an inductor, which creates a magnetic field. This magnetic field is then employed to provide the voltage regulation. As the inductor is switched from charging to discharging, the stored energy in the magnetic field is used to reduce the output voltage. This process is repeated in a cycle, allowing the JRW060A0F to maintain a constant output voltage.

The JRW060A0F also uses an internal feedback system to detect any changes in the output voltage and adjust its parameters accordingly in order to maintain a constant output voltage. It also features several protections such as over-current protection, over-temperature protection, short-circuit protection, and leading edge modulation which help protect the device from any unexpected occurrences.

Conclusion

The JRW060A0F is a multi-output non-isolated DC-DC converter capable of supplying multiple higher voltages. It is designed with a wide range of features such as flexible and robust short circuit protection, high-speed transient response, no switching noise, and leading edge modulation for better protection. It is also ideal for multi-card or distributed power applications. The working principle of the JRW060A0F is that it reduces the input voltage to generate the desired output voltage using an inductor and internal feedback system. This makes it an ideal solution for many power supply applications.
