• Introduction

The PMIC – Power Supply Controllers, Monitors series includes a variety of power supply controllers, monitors and other related ICs that are capable of providing a regulated output voltage from an input voltage source. Among these, the MP6920DN-LF is a relatively recently released IC which is particularly suited for low Start-up and fast Transient response applications. In the section ahead, we will take a closer look into the application field and working principle of the MP6920DN-LF.

• Application Field

The MP6920DN-LF is a high performance, highly accurate, linear regulator IC which is optimized to provide a low dropout voltage, fast transient response and fast start up time. It is particularly suitable for applications operating on low supply voltages like Notebook PC’s, PDAs, MP3 players and Digital Still Cameras.Made with a CMOS process, the MP6920DN-LF has a maximum output current of 3 A and can operate on an input voltage ranging from 4.4V to 34V. It is capable of providing a voltage output range between 1.2V and 30V at up to 4A. Furthermore, the IC is also equipped with built-in safety features that protect against over voltage, over-current and over-temperature conditions.

• Working Principle

The MP6920DN-LF is essentially a voltage regulator whose working is based on the very simple principle of transmitting the input voltage through an adjustable resistance, and thus, regulating the output voltage. In order to effectively carry out this regulation, the IC utilizes three main control modules: an Error Amplifier (EA), an Over Voltage Protection (OVP), and a Voltage Reference (VR).The EA controller monitors the output voltage with respect to the reference voltage (VR) in case of any discrepancies; and accordingly adjusts the resistance of the voltage scaler to modify the output voltage. The OVP controller protects against over voltage conditions by responding to an input supply voltage surplus and feeding this back as a reduction in output current to the EA.The combination of the two controllers means that the MP6920DN-LF can regulate the output voltage within a very fine degree, in addition to providing safety features that guard against a multitude of potential hazards. This coupled with its superior transient response ensures reliable and stable operation for a large variety of application scenarios.

• Conclusion

In summary, the MP6920DN-LF is a power supply controller and linear regulator IC that is designed to provide a fast start up time, low dropout voltage and fast transient response for applications operating on low voltage supplies. With a maximum output current of 3A and an input voltage range of 4.4V to 34V, the IC is able to effectively adjust resistance within a highly precise degree and is also equipped with safety features for a safe and reliable operation.
