The AET01CC18-L are DC-DC converters designed to be used in a wide variety of applications, such as in power management systems, distributed power systems, embedded systems, automotive, solar, and aerospace applications.

The AET01CC18-L is a high-performance, 4.5V to 24V input, isolated, self-centered, wide input voltage, wide output voltage range, and single-output module. It is ideal for applications where electrical isolation is required between the input and output of the converter, such as in distributed power systems.

The AET01CC18-L has a wide input voltage range of 4.5V to 24V and operates at 200kHz switching frequency. It has a high efficiency of up to 94%, high power density, and low output ripple and noise. The special design of the module reduces EMI, allowing it to meet both EMC and EMI standards.

The AET01CC18-L is designed to provide reliable, continuous power conversion and has a wide operating temperature range of -40 to 100°C. It has a wide output voltage range of 9.5V to 18V, with an adjustable 0-20V output voltage range. It is protected against short-circuit and overtemperature conditions.

The AET01CC18-L features a safety-isolated input-output structure. It also features a wide dynamic response bandwidth with fast transient response and recover times. This makes it more suitable for use in applications that require a fast switching response and precision regulation.

The working principle of the AET01CC18-L DC-DC converter is based on the buck converter design. In this type of converter, an input voltage is rectified and filtered. The filtered voltage is then used to drive a high-frequency switch, which then charges a storage inductor. The storage inductor is then discharged through a low-resistance device such as an FET, which converts the energy stored in the inductor into a regulated output voltage at the output.

The operation of the AET01CC18-L consists of the following steps: first, the input supply voltage is rectified and filtered so that the resulting output voltage is of constant amplitude and is ripple free. This is then used to drive a power switch, usually implemented as a transistor, which regulates the amount of energy delivered from the input source to the inductor. Secondly, the power switch then charges the storage inductor with the input voltage, when the switch is ON. The switch is then turned OFF, when the inductor has reached its desired value.

Finally, the inductor then discharges its energy through a low resistance device, such as an FET, converting the energy into a regulated output voltage at the output. This output voltage is then compared to a reference voltage, and is adjusted using a feedback loop to maintain a constant and accurate output voltage.

Overall, the AET01CC18-L is an attractive choice for applications that require a wide input voltage range, high performance, low noise and good power efficiency in a compact package with electrical isolation between the input and output. The working principle of this module makes it suitable for applications that require fast switching response, precise regulation and low output ripple.
