Working Principle

The LMR12010YMKX/NOPB works on the principle of switching action. This means that it switches the output between a high and low state in order to regulate the output voltage. The switching action is achieved by using a voltage-controlled circuit, which is in turn driven by an external voltage source. The voltage source drives the voltage-controlled circuit, which switches between the high and low states. When the external voltage source is higher than the output voltage, the circuit switches to the high state, providing additional energy to the load. When the voltage source is lower than the output voltage, the circuit switches to the low state, cutting off the load from the input voltage.

Conclusion

The LMR12010YMKX/NOPB is a high performance synchronous rectified buck switching regulator that combines high efficiency, low output ripple and EMI and high output current. Its wide input voltage range and pulse width modulation architecture enables it to operate over a wide range of conditions. Its programmable current limit and compact package makes it an ideal solution for a range of high power applications.
