The MP9115DQT-LF-Z is an efficient, high frequency, high current DC-DC step-down synchronous switch mode power supply (SMPS) regulator. It provides an efficient, low noise, and stable voltage output. The MP9115DQT-LF-Z is ideally suited for applications such as servers, laptops and other applications requiring high voltage and current. It is a versatile and reliable source of power for a variety of systems.
Application Field
The MP9115DQT-LF-Z new generation of power step-down DC-DC switch mode power supply (SMPS) regulators are suitable for a wide range of applications. It is ideal for providing low-noise and stable power for product design, data acquisition and digital process control systems, as well as battery-operated, mobile, and distributed-power systems. This SMPS can also be used to provide regulated power for LCD displays, and industrial motor control applications.
The MP9115DQT-LF-Z integrates all necessary protection circuitry, and has the added advantage of both Buck (reducing the input voltage) and Boost (increasing the input voltage) operating modes. In Buck mode, the MP9115DQT-LF-Z can produce a regulated output voltage from 0.8V to 20V and with the addition of external resistors, the output voltage range can be extended up to 28V. In Boost mode, the output voltage can be set between 28V to 40V. The MP9115DQT-LF-Z regulator is rated to have an output current of 1.2A and can provide up to 2.5A with an external P-MOSFET.
Working Principle
The MP9115DQT-LF-Z DC-DC step-down synchronous switch mode power supply (SMPS) regulator operates on the principle of current-mode control. The voltage across the current sense resistor is monitored and is used as the feedback loop for controlling the output voltage. The MP9115DQT-LF-Z also employs a proprietary patented high frequency switching architecture that helps reduce overall power losses. The power stage consists of two external MOSFETs, an inductor and two capacitors. The MP9115DQT-LF-Z regulates the output voltage by controlling the MOSFETs to switch on and off in response to the voltage across the current sense resistor. The external components of the power stage are precisely matched with the core voltage of the regulator to minimize power losses.
The MP9115DQT-LF-Z also incorporates a patented LPF (Low-Pass Filter) circuit which helps reduce high-frequency EMI (Electromagnetic Interference) and provides a stable output voltage. The LPF circuit also helps reduce output noise, ripple and EMI emissions. The LPF is adjustable and can be adjusted to reduce noise, ripple, and EMI emissions to acceptable levels.
The MP9115DQT-LF-Z also has multiple input under-voltage and over-voltage protection features. It also incorporates an adjustable current-limit circuit which helps protect the power stage from over-current conditions. In addition to the voltage and current regulations, the MP9115DQT-LF-Z also includes soft start, output overtemperature protection and output under-voltage protection features.
Overall, the MP9115DQT-LF-Z DC-DC step-down synchronous switch mode power supply (SMPS) regulator is an efficient, high current, and highly accurate power supply for server, laptop and other systems. It is ideal for a variety of applications requiring a reliable and regulated power source.
