Working Principle of the MINT1180A2875K01 DC-DC Buck Converter

The MINT1180A2875K01 is a pulse-width modulation (PWM) type DC-DC buck converter with continuous conduction mode (CCM). Its working principle is based on the boost topology and thus has a constant on-time (COT) control. In this type of converter, the input AC voltage is first rectified and then smoothed with an LC filter and voltage regulator. The voltage regulator provides the control signal for the PWM controller to switch the switching regulator on and off cyclically. When the regulator is on, the energy from the input voltage is stored in the inductor, and when it is off, the energy stored is released into the load. The output voltage is regulated and maintained across a wide range of load conditions with the help of the PWM controller and feedback circuitry. The MINT1180A2875K01 is a low-dissipation DC-DC buck converter that has a built-in constant-on-time control.

To summarize, the MINT1180A2875K01 is a single output, wide input voltage AC/DC switch mode power converter that is suitable for industrial, home and office, consumer electronics, and medical device applications. It is designed with efficient PWM control, a low no-load power consumption, and features overvoltage, overload, and over temperature protection, making it safe and reliable. Also, its working principle is based on the boost topology and utilizes the COT control concept for efficient operation.
