DC-DC converters are indispensable components in circuit designs. PWR1301AC, a well known DC-DC converter designed and developed by Poweron Corporation, is widely used in many circuits for its high reliability, compact size, and excellent performance. In this article, we will explore the application field and working principle of PWR1301AC DC-DC converter.

It is an advanced DC-DC converter with ultra-wide input voltage range and output voltage range. It accepts input voltage from 5V to 36V and provides output voltage from 3.3V to 28V. This range makes it applicable to various fields such as communication system, electric system, consumer electronics, automotive electronics, etc. Other than that, it has an integrated power switch with adjustable current limiter and short-circuit protection. It can provide great protection for your circuit from power surges and sudden shorts. It also has thermal shutdown protection and over-voltage protection to ensure its stability and reliability. It also remains stable under ripple voltage.

Now let\'s turn to the working principle of this DC-DC converter. PWR1301AC is a buck DC-DC converter which means it reduces the input voltage to produce lower output voltage. It is a highly-integrated device which consists of an inductor, an output rectifier, a current sense resistor, a power switch and etc. Its working principle can be divided into two stages. The first stage is the power resistor which is responsible for the current limitation of the converter. It provides a reference current to the switch, which is used to turn on and off the switch accordingly and adjust the operation of the PWR1301AC. The second stage is the inductor which is used to store electric energy in magnetic fields. When the switch is turned on, the inductor will store electric energy and then when the switch is turned off, the inductor will discharge its energy and the output rectifier will convert the inductor\'s discharging energy into an output DC voltage.

In conclusion, the PWR1301AC is a widely used DC-DC converter with various protective features and excellent performance. It has ultra-wide input and output range which makes it applicable to many fields. Moreover, its working principle utilizes a power resistor to limit the current and an inductor to store electric energy which are then converted into an output DC voltage. With its high reliability and compact size, the PWR1301AC is undoubtedly an ideal choice for any circuit design.
