MP2013AGG-P is a type of linear voltage regulator typically used in PMIC (power management integrated circuits). It is suitable for Intel 3 Phase Power/Jump Start Micro Desktop Current Testing (DCT) system and other applications that require low-power auto-start. It is a multi-phase, self-powered, multi-output voltage regultor chip that is able to adjust the output volts of the input voltage.

The MP2013AGG-P voltage regulator features an adjustable output voltage range from 0.1V to 5.5V. This is significantly higher than most other linear voltage regulators. It also has an adjustable operating temperature range from -40 °C to +125 °C and a wide input voltage range from 4V to 17V. It is made up of N-Channel MOSFETs and is a pulse-width modulated (PWM) type of regulator. The internal circuitry of the chip features short-circuit, over-current and over-voltage protection.

The primary function of the MP2013AGG-P voltage regulator is to maintain the output voltage independent of load and input voltage conditions. This is essentially done by adjusting the current through the MOSFETs. The adjustability of the output voltage enables it to be used in a variety of applications including desktop and server power supplies, mobile device power supplies and audio power supply amplifiers.

In order to determine how the MP2013AGG-P voltage regulator works, it is important to understand the basic principles of voltage regulation and how they are applied in this device. The main function of any voltage regulator is to subtract the input voltage from a fixed reference voltage and convert the difference into a fixed, regulated output voltage. This process is known as " Regulation”.

The MP2013AGG-P voltage regulator applies this process by utilizing two transistors, a "Regulator" and a "Feedback" transistor. The regulator transistor is set to produce a preset voltage, which is known as the reference voltage. The feedback transistor is then used to compare the preset voltage of the reference transistor to the actual input voltage. When the actual input voltage is less than the reference voltage, the difference is reduced by increasing the voltage of the feedback transistor. Conversely, when the actual input voltage is higher than the reference voltage, the difference is reduced by decreasing the voltage of the feedback transistor.

The MP2013AGG-P voltage regulator further applies the principles of voltage regulation by means of pulse-width modulation, which is a type of timed waveform control. When the regulator is energized, the pulse-width modulation of the MOSFETs generates a repeating waveform that adjusts the output voltage. By increasing or decreasing the pulse width of this waveform, the voltage of the output can be adjusted according to the requirements of the application.

In addition to the pulse-width modulation, the MP2013AGG-P voltage regulator also utilizes two additional functions to ensure that the voltage stays within pre-determined limits. These are over-voltage protection (OVP) and under-voltage protection (UVP). Both of these functions are designed to detect when the output voltage is outside the range of the preset voltage, and shut down the regulator. This ensures that the output voltage remains within a predetermined range, regardless of load or input conditions.

In conclusion, the MP2013AGG-P voltage regulator is a versatile, multi-output device that is capable of providing adjustable, regulated output voltages. It is suitable for low-power automatic start applications and features short-circuit, over-current, and over-voltage protection. The regulator utilizes both pulse-width modulation and over-voltage/under-voltage protection to guarantee safe, regulated output voltages within a preset range.
