DC DC Converters

DC-DC converters are devices that convert direct current from one voltage level to another. The UWS-3.3/15-Q48PM-C is a type of DC-DC converter, specifically, a synchronous buck-converter. It is a power module designed for use in distributed power architectures, and offers efficient and reliable power delivery.

Application Field and Working Principle

The UWS-3.3/15-Q48PM-C is designed for use in industrial, medical, communication, transportation, and consumer electronic applications. It accepts an input voltage of 4.5V to 14V and provides an output voltage of 3.3-4.2V. It is able to handle up to 15A of current, and has an efficiency of up to 95%.

The UWS-3.3/15-Q48PM-C uses a synchronous buck-converter topology, which is an efficient method of transforming power from a higher voltage to a lower one. The converter works by switching the input voltage at a high frequency, and then using the output inductor to average the voltage and provide a steady output voltage. This high frequency switching allows for more power to be converted than there is available on the input side, allowing for higher efficiency.

The UWS-3.3/15-Q48PM-C consists of an insulated metal substrate package which houses the synchronous converter. The device contains both a high and low side MOSFET driver, as well as a current sense amplifier, a current limiter, and an overvoltage protection circuit. The device also contains a control circuit which regulates the output voltage according to the input voltage and sensed load current.

The UWS-3.3/15-Q48PM-C features an integrated shunt regulator, which allows for an adjustable output voltage from 3.3V to 4.2V. The output voltage is adjustable using a voltage divider, which can be set up to provide a given output voltage. The device also features a minimum on-time of 100ns and a maximum off-time of 100ns, which allows for precise control of the duty cycle.

In addition, the UWS-3.3/15-Q48PM-C features thermally enhanced power handling and reliability. The device is optimized for low noise operation, and has an extendable operating temperature range of -40C to 110C. It also has an integrated sense resistor for monitoring output current. The device is protected by a thermal shutdown circuit which will shut down the power when the temperature of the device exceeds specified limits.

The UWS-3.3/15-Q48PM-C is a highly efficient, reliable, and cost effective DC-DC converter designed for use in a variety of applications. It features solid state construction, and can operate over a wide range of temperature and input voltages. Its adjustable output voltage feature and low noise output make it well suited for a variety of industrial, medical, communication, transportation, and consumer electronic applications.
