Working Principle

The LM2647EVAL is designed to interface two DC power sources which, once connected, operate in a fixed frequency, switch mode synchronous DC-DC converter. It works by continuously cycling the charge on the output capacitor at a rate which is determined by the oscillator frequency. The primary control circuit in the LM2647EVAL comprises of a differential amplifier with its own output. This output is fed back into the error amplifier to control the internal switching device and also for voltage modulation. The device is designed to pioneer the latest advancements in operating principle, packaging, and peripheral circuitry.

The LM2647EVAL also includes protection features over current, over temperature, and under voltage. The integrated circuit has wide range of available versions offering different selections of output levels and insulated options to fulfill specific design needs. The selection of a given output voltage level is determined by the voltage setting resistors connected to the pins of either the current mode or voltage mode. By setting the Oscillator frequency, it\'s possible to program the conversion frequency of the device.

In conclusion, the LM2647EVAL evaluation board offers the engineer the opportunity of exploring the very unique features of the LM2647. With its high power efficiency and reliable performance, it can simplify designs in a wide range of applications.
