Regulated DC power is essential for powering today’s electronic devices and many industrial applications. One of the most advantageous ways of the voltage and current regulation is by using a DC DC switching regulator. The LMR12010YMKE/NOPB by Texas Instruments is a good example of a modern DC DC switching regulator.

Application Field

The LMR12010YMKE/NOPB DC DC switching regulator is designed as both a high-current linear as well as a switching regulator. As such, it is suitable for a wide array of systems, including mobile phones and other portable devices, industrial loads, and other high power applications. It works by receiving an input voltage and comparing this value with a fixed preset voltage in the regulator circuit. If the input voltage is lower than the preset voltage, the output voltage will be increased, and if the input voltage is higher than the preset voltage, the output voltage will be lowered. This makes the device reflect changing loads without the need for manual adjustment or external intervention.

Working Principle

The LMR12010YMKE/NOPB switching regulator works by taking the input voltage and converting it into a low-voltage, high frequency signal using an internal oscillator. This signal is then used to drive a power switch which controls the output voltage of the regulator. When the power switch is “on”, the output voltage is determined by the duty cycle of the signal sent to the switch via the oscillator. When the power switch is “off”, the output voltage is determined by the input voltage. Thus, by correctly controlling the duty cycle of the switch, the output voltage of the regulator can be accurately set to a desired value.

The LMR12010YMKE/NOPB regulator also features a variety of protection and control capabilities. It has a current-limited output protection along with both over-temperature and over-voltage protection. It also features adjustable soft-start and frequency hopping features, allowing for fine-tuning at a system level. On top of that, the regulator is from an integrated MOSFET, meaning that it does not require any external circuit components for operation. This makes the regulator ideal for use in space-constrained projects.

Conclusion

The LMR12010YMKE/NOPB DC DC switching regulator by Texas Instruments is an excellent example of a modern high-power voltage regulator. It is highly capable, with a wide range of protection and control capabilities, and it is integrated with an MOSFET meaning that it requires no external components for operation. It is suitable for use in a wide range of devices, including mobile phones and other portable devices, industrial loads, and other high power applications.
