DC-DC converters play an important role in many industrial and consumer applications due to its capability to convert one DC voltage level to another, or from AC to DC and vice versa. A type of DC-DC converter which has grown in popularity in recent years is the NMK1209SAC. This article will discuss details of this device, its application fields and the working principles.The NMK1209SAC is an interleaved high frequency, non-isolated synchronous buck converter. It contains two switching buck regulators with a field-programmable version connected in parallel (called an interleaved configuration) to double the current that can be obtained from a converter without increasing the power losses. It is a compact, small size component with an operating voltage range from 24V to 36V and a wide operational temperature range of -40 to +125C. The output voltage is adjustable from 0.8V - 1.8V with an output current of up to 20A and a maximum power of 70-80W. It is also designed to work at a switching frequency of up to 4.5 MHz, making it suitable for high-frequency applications.The device is mainly used in off-line power conversion, such as DC-DC converters, DC-AC inverters, and AC-DC rectifiers. It is particularly suited for applications such as point-of-load (PoL) and embedded systems, where precise, efficient power is required. The high frequency and interleaving design improves efficiency and reduces design complexity, making NMK1209SAC an attractive choice for such applications.The working principle of the NMK1209SAC is that when a DC voltage is applied to it, the switching circuit will turn on and off periodically to convert the DC voltage input to a lower voltage at the output. The switching of the circuit is controlled via the Input Voltage Supervisor, which is a closed loop system that maintains the output voltage at the desired level. The current-limit circuit ensures that the total power drawn from the device does not exceed the maximum rated current. The conversion process takes place with a high frequency and includes several steps. Firstly, the incoming voltage is rectified and filtered to remove noise and harmonics. Secondly, the input is then converted to a higher frequency through the pulse-width modulation (PWM) circuit. Next, the output current is sensed and the voltage is regulated to a stabilized output voltage. Finally, the high frequency signal is then converted back to a DC voltage output from the device.In conclusion, the NMK1209SAC is a highly efficient, compact and reliable DC-DC converter with a wide range of applications. It is suitable for high-frequency applications and provides excellent power conversion performance. The device also includes features such as wide output voltage and temperature range, current-limit circuit, and input voltage supervisor to ensure reliable operation.
