MP3415GG-P Application Field and Working Principle
The MP3415GG-P is a monolithic switching regulator from Micrel and it belongs to the PMIC (Power Management IC) Voltage Regulators and DC DC Switching Regulators family. This device has been designed to reduce costs and simplify power supply design by providing an integrated solution of a step-up DC/DC converter, dual and single output linear regulators, as well as various features and protection. Moreover, the MP3415GG-P delivers both an adjustable and a fixed output with a high efficiency, allowing the system to operate in battery driven and high-current applications, such as those of the TV, Servers, Automotive, Notebook and Desktop.
Overview of the MP3415GG-P
The MP3415GG-P is a high performance, low input voltage, 1.5 A DC/DC converter plus dual and single output linear regulator. It integrates a 1.5A step-up DC/DC converter with a dual-output linear regulator (3.3V/1.8V) and a single-output linear regulator (5V), allowing the system to operate with a maximum output of 5.1V.
The MP3415GG-P features integrated, high efficiency, low dropout, fixed 3.3V and 1.8V linear regulator outputs, as well as an adjustable output ranging from 1.25V to 5.1V. Hence, it has the capability to support multiple rail configurations in most applications, thus reducing the number of external discrete components.
This device is capable of handling up to 1.5A currents, and it also provides ultra low quiescent current to maximize the battery life. Additionally, the MP3415GG-P includes a soft start feature which prevents in-rush current and current limit as well as over temperature protection and short-circuit protection.
Apart from these features, the MP3415GG-P is able to accurately regulate the output voltage with a precision of 0.5% over temperature and line variations. Furthermore, the device offers high-speed turn on and turn off capabilities, thus providing a high frequency ripple that can suppress the output load transients caused by the load step-up/down. Moreover, the device is also capable of operating with a low dropout voltage, meaning that the input voltage can be lower than the output voltage, thus saving power and cost.

Applications of the MP3415GG-P
The MP3415GG-P is an ideal device for applications such as TV, Servers, Automotive, Notebook and Desktop that require high-current and low-input applications. Additionally, it can be used in embedded systems that require precise regulation for a variety of logic power supplies.
Working Principle of the MP3415GG-P
The MP3415GG-P is a switching regulator which works based on a switching technique that is used to convert a direct-current (DC) input into a DC output with desired specifications of voltage and current. This technique works by using two or more switches that alternately turn on or off to create a regular waveform out of the power supply. This waveform is then filtered to reduce any ripples and create a clean DC output.
The MP3415GG-P features a Buck topology, meaning that the output is obtained by switching the input voltage to ground. Thus, when the switch turns on, the inductor accumulates energy, and when the switch turns off, the energy previously stored in the inductor is released. This produces a filtered direct current at the output, with a voltage that is proportional to the input voltage, depending on the duty cycle of the switching.
The MP3415GG-P is intended to provide both a step-up DC/DC converter and dual and single output linear regulators. Thus, it includes a PWM (Pulse Width Modulation) controller which, based on the error amplifiers that sense the difference between the output voltage and the feedback voltage, regulates the duty cycle of the switch. This allows the system to adjust the output voltage according to the voltage required by the load.
Finally, the MP3415GG-P also includes protection features such as over temperature protection, current limit protection, and short-circuit protection. These features help protect the system from any malfunction which could lead to circuit malfunctions.
Conclusion
The MP3415GG-P is a precise, low input voltage, 1.5 A DC/DC converter plus dual and single output linear regulator belonging to the PMIC (Power Management IC) Voltage Regulators and DC DC Switching Regulators family. The device is ideal for applications such as TV, Servers, Automotive, Notebook and Desktop, as well as embedded systems that require precise regulation for a variety of logic power supplies. Moreover, the MP3415GG-P integrates a 1.5A step-up DC/DC converter, dual and single output linear regulators, protection features, and a precision output voltage of 0.5% over temperature and line variations.
