MP2141NGTF-15-Z Application Field and Working Principle

Introduction

DC/DC switching converters, also known as switchers, are based on a wide range ofregulation technology and circuit topologies to efficiently convert voltage in therange of 3V to 60V, giving the user enhanced flexibility and system design options.These converters have created a powerful class of DC/DC regulator, which happensto be the MP2141NGTF-15-Z.

MP2141NGTF-15-Z Application Fields

MP2141NGTF-15-Z is a modern synchronous buck currentmode PWM (pulse width modulation) controller integrated specifically for applications such as cellphone audio, portable devices and Smart TVs. It features a high-frequency (560kHz)and wide voltage range (4.5V - 60V) operation. The MP2141NGTF-15-Z is available in a6-lead SOT23 package and includes a bootstrap supply.

MP2141NGTF-15-Z Working Principle

The MP2141NGTF-15-Z follows a high-performance current-modecontrol architecture. The PWM modulator computes the duty cycle of the outputswitching regulator based on an internal or external voltage comparator and anoscillator generator. External resistors are used to set-up the ripple rejectionratio and the MOSFET gate drive.

The inductor current of the switching regulator is sensed by anexternal resistor. The MP2141NGTF-15-Z provides programmable current limit,cycle-by-cycle current limiting and auto recovery from the over-current mode. Optonal zero-current-detection is also available.

The MP2141NGTF-15-Z also features thermal shutdown forwindings as well as output capacitor temperature sensing system. The part alsofeatures a fast transient response, which allows the user to optimize the systemperformance to meet the specific requirements.

Conclusion

In conclusion, the MP2141NGTF-15-Z is a synchronous buck current-modepulse width modulation controller integrated specifically for applications such ascellphone audio, portable devices and Smart TVs. With its high-frequency (560kHz)and wide voltage range (4.5V - 60V), it provides users with enhanced flexibilityand system design options.
