Working Principle

The DA18-150MP-M series is a DC-DC converter that converts an input voltage of 11 to 34V DC into an output voltage of 3.3 to 24V DC. The converter uses a switching technique that maintains the input voltage within a certain duty-cycle, and then uses the same cycle to control the output voltage. The switching frequency is typically 5-15 kHz. The switching works by controlling the cycle of the transistor conduction, and the output voltage and current are tightly regulated through pulse width modulation (PWM). The output voltage can be accurately regulated to within 1% or less of the desired voltage.

The circuit of a DA18-150MP-M DC-DC converter includes a power transistor, inductor, filter capacitor, and a control circuit. The power transistor is connected in series with the inductor and the input voltage. When the power transistor is on, current flows through the inductor and energy is stored. When the power transistor is off, the inductor releases energy to the filter capacitor, thus creating a regulated output voltage.

The power transistor is driven by a control circuit, which generates a PWM signal. The PWM signal determines the duty cycle, which is used to regulate the output voltage. The control circuit also monitors and regulates the output voltage, as well as providing protection features such as over-voltage and short circuit protection.

Conclusion

The DA18-150MP-M series of AC/DC desktop and wall adapters provide reliable and cost-effective power solutions for a variety of applications. This series offers a wide input voltage range, high efficiency, and multiple protection features. Furthermore, the series works on the principle of regulating the output voltage through PWM. Therefore, this series is an ideal choice for applications in the industrial, medical, automotive, and consumer electronics sectors.
