QBS050YE-A

A DC/DC converter is an electric circuit that converts a portion of a direct current (DC) voltage to a different DC voltage level. They are often used to power electronic devices from a variety of sources. One common example is in automobiles, where a DC/DC converter is used to convert 12V from the car battery to 5V to power most of vehicle\'s electronics, including the engine control unit and in-car entertainment systems.

These converters are also widely used in consumer electronics, industrial machinery, solar and wind energy storage, and in aviation applications. On aircrafts, they are used to convert the high-voltage, high-current primary power cable from the engines to a lower voltage, lower current to power the systems in the cockpit.

The QBS050YE-A is a DC/DC converter specifically designed for low-power applications. It is a buck-type converter with the ability to supply up to 5A of current at a maximum power output of 25W. It has a wide input voltage range from 4.5V to 36V, making it ideal for a variety of applications.

The QBS050YE-A employs synchronous rectification technology to provide higher efficiency conversion. This technology uses an external power supply to control the switching of the switch MOS device, resulting in lower operating temperature in comparison to non-synchronous rectification. This converter also implements an active frequency jittering technique to reduce the output voltage ripple. It features adjustable output voltage (0.8V to 8.5V) and current limiting function (within ±5%).

The QBS050YE-A is a highly efficient and highly reliable DC-DC converter. It is designed to operate in a wide range of temperatures from -40ºC to 85ºC and features an EMI level of Class B, making it suitable for most applications. Moreover, the device is offered with a range of package options, including a miniature SIP housing, to fit into restrictive spaces.

In conclusion, the QBS050YE-A is a high performance DC/DC converter designed for low power applications. It features a wide input voltage range of 4.5V to 36V and provides a maximum output current of 5A, making it a popular choice for a wide range of electronics applications.
