The LMR12007XMK is suitable for automotive and industrial applications where the voltage regulation of multiple output supplies is required. It is also suitable for applications such as power supplies, gateway devices, routers, laptops and desktop computers.

Working Principle

The LMR12007XMK works by converting input voltages into a regulated output voltage. The regulator works by using a buck switching regulator, which consists of a power MOSFET switch and an inductor. When the switch is opened, a current is created in the inductor, storing energy which is then delivered to the output, when the switch is closed.

The output voltage is regulated using PWM or PFM. In PWM mode, the MOSFET is switched on and off at a controlled frequency, and the output voltage is regulated by controlling the duty cycle of the switch. In PFM mode, the MOSFET is switched on and off at a variable frequency, with the output voltage being regulated by varying the frequency.

The LMR12007XMK is designed with a wide range of protection and control features, such as over-current and over-temperature protection and input under-voltage lockout. It is also capable of delivering up to one amp of output current, making it suitable for a wide range of applications.

Conclusion

The LMR12007XMK is a versatile, low-side step-down DC–DC converter, suitable for use in many applications. It is capable of providing a wide range of output voltages and dynamic efficiencies, and can be used in automotive, industrial and consumer applications. It has a wide range of features and protection, making it suitable for a wide range of applications.
