AC/DC converters are devices used to convert alternating current (AC) to direct current (DC). The CLC175US48-M is a High Density Step-Down AC/DC converter. This type of converter takes electrical input of higher voltage, and output at a lesser voltage. The CLC175US48-M is a high-density, non-isolated, point-of-load (POL), buck converter. It is ideal for applications where required voltage and current must be achieved with minimal size, weight, and cost.

The CLC175US48-M has a maximum power output of 175 watts, with a voltage in range from 4.5V – 48V and a maximum output current of 8.75A. This wide input voltage range helps support products which are powered by AC or DC. It is also protected against over voltage, over current, over temperature, and short circuit. This brings improved reliability and system safety.

The CLC175US48-M utilizes an innovative and proprietary SOT-89 package. This small size helps save space while delivering high power density of 5.5W/cm³. It also uses synchronous rectification for improved efficiency and is rated in efficiency in the range of up to 90.5%.

The CLC175US48-M has an operating range from -40^oC to +125^oC for its full power output, allowing it to work in harsh environments. It is certified for use in Industrial, Automotive, and Medical applications.

The operating principle of the CLC175US48-M is based on a voltage loop that controls the average inductor current by controlling current output from a high frequency switching circuit. The high frequency switching circuit, commonly referred to as a buck converter, receives input voltage and current from the AC or DC power source and outputs the voltage and current at the lower voltage output level.

The most important element in the voltage loop is the feedback loop. The feedback loop provides the key element of maintaining the desired output voltage. The feedback loop controls the switching circuit by low-side and high-side drivers. When the output voltage exceeds the voltage reference, it signals to the switching circuit to reduce the duty cycle so that the output voltage and current will remain at the desired levels.

The CLC175US48-M solution is a reliable and efficient, low-cost, high-performance solution for applications that require high-density AC/DC converters such as those used for high-power (>55W) CPUs, GPUs, VRMs, FPGAs, power amplifiers, electric motors, servo drives, and AC/DC adapters. It is a great choice for power applications in both the industrial and medical industries.
