DC DC Converters
DC to DC converters are electronic devices that take a DC voltage and convert or adapt it to a DC voltage of different magnitude and/or different electrical characteristics. DC to DC converters are used in many applications, such as providing power conversion from a primary DC source to a secondary load or providing a DC to DC interface between two pieces of electronic equipment. DC to DC converters can be classified into two broad categories based on their ability to produce an output voltage with a specific phase relationship with the input voltage. These categories are isolated and non-isolated DC to DC converters.
The CHS80483R3 is a DC to DC converter that belongs to the non-isolated category. This device is a synchronous buck type DC to DC converter that works by switching an inductor\'s current on and off to produce a variable output voltage. This can be achieved by varying the duty cycle of the applied switching signal. The remarkable feature of this converter is that it is highly efficient, providing greater than 85% peak efficiency over a wide range of input and output voltages. It has a programmable output voltage, a wide operating voltage range, and can provide both a no-load and full-load current limit.
The CHS80483R3 is suitable for a wide range of applications. This DC to DC converter can be used in automotive, industrial, and space applications requiring extreme precision, such as motor control and power supply systems, solar cell systems, and fuel cell systems. The converter can also be used in applications that require high isolation voltage, ruggedness, and long-term reliability. Moreover, it can be used in low voltage power supply and battery-powered systems. In addition, it can also be used for single-phase grid-tied inverters, portable power supplies, LED lighting, and medical device power supplies.
The working principle of the CHS80483R3 is quite simple. When the converter is enabled, a variable-frequency, fixed-duty-cycle pulse-width-modulation (PWM) signal is generated, which controls the on and off operation of the Zener-diode-free N-channel MOSFET switch. The MOSFET turns on and off the inductors to convert the energy from the input voltage to create the output voltage. During each switching cycle, the inductor current ramps up and ramps down, and the output voltage is determined by the magnitude of the switching frequency and duty cycle. To control the output voltage, the PWM loop tracks and regulates the output voltage in order to maintain the set point voltage.
In summary, the CHS80483R3 is a non-isolated type DC to DC converter that is suitable for a wide range of applications. This device is highly efficient and can provide a programmable output voltage. It works by pulsing the N-channel MOSFET at a variable frequency and a fixed duty cycle based on the input and output voltage. This converter is ideal for motor control and power supply systems, solar cell systems, and fuel cell systems, among other applications.
