The LM2660-7 is an AC/ DC converter, a device that is capable of converting an alternating current (AC) source into a direct current (DC) source. The converter makes use of a synchronous buck-boost converter circuit to increase or decrease voltage likely as required. The circuit also provides for low and high frequency operation, enabling changes in the output voltage to occur at a slower rate than with traditional AC/DC converters.

The LM2660-7 works by converting a waveform input from an AC source into a steady DC output voltage. It has a fixed voltage setting of 28V with an adjustable voltage range of 28V to 65V. The converter also utilizes a switching frequency of up to 100kHz, and is capable of providing an output voltage that is either higher or lower than the input voltage.

The system works by using a transformer to step down incoming voltage after which a rectifier and filter circuit converts the AC to DC. The DC is then applied to a pair of switches in a switch-mode topology, which regulates the incoming voltage level to the output voltage. An on-chip driver enables synchronization and accurate voltage control.

The LM2660-7 is suitable for a wide range of applications, from general purpose power systems and on-board automotive systems to telecom, industrial and gaming applications. Its high efficiency, wide input voltage range and low output voltage ripple make it ideal for applications where high performance and reliable power is needed. Its UL60950 and CE compliant design also makes it suitable for use in industrial and medical applications where safety is a significant concern.

The LM2660-7 AC/DC converter operates in two principal modes – switching mode and analog mode. In switching mode, the voltage is electronically regulated with few components. This mode is typically used for high efficiency, high current applications. On the other hand, in analog mode, voltage is regulated with less components and is best for low-noise and ultra-low ripple applications.

The main features of the LM2660-7 AC/DC converter include synchronous rectification to minimize power losses, extremely wide operating temperature range from -40°C to +125°C, thermal protection to prevent overheating, over-voltage and under-voltage protection, and 100 percent burn-in tests. These features make the LM2660-7 an ideal solution for a wide range of applications.

In conclusion, the LM2660-7 is an AC/DC converter that utilizes a synchronous buck-boost converter circuit to increase or decrease voltage likely as required. Its adjustable voltage range and wide operating temperature range make it ideal for use in a variety of applications, from general purpose power systems and on-board automotive systems to telecom, industrial and gaming systems. Its reliable and safe design, along with the features of synchronous rectification, thermal protection and over-voltage/under-voltage protection, make it a great choice for applications that require high performance and reliable power.
