DC-DC converters are systems that transform direct current (DC) from one voltage level to another within a predetermined tolerance range. The MPM3805GQB-18-P is a DC-DC converter specifically designed for intermediate bus architecture (IBA) applications, such as Advanced Telecommunications Computing Architecture (ATCA) base platform servers, and operates in either ON/OFF non-isolated or step-up/step-down isolated voltage modes.

The MPM3805GQB-18-P features wide input voltage range and wide output voltage remaining within the input voltage range, which makes it suitable for a wide range of applications. It can operate from -36V to -72V DC input and provides 0.5V to 7V DC output voltage, and it is also capable of low-side common ground bias.

The MPM3805GQB-18-P can be used in compact communication and computing platforms, including servers. It is ideal for powering large arrays of digital signal processors. The MPM3805GQB-18-P, with its efficient switching architecture, helps reduce heat dissipation, thus allowing the system designers to reduce the size of their thermal solutions.

The MPM3805GQB-18-P includes a highly configurable advanced power-management controller (PEMC). It offers a number of features, such as programmable over-voltage, over-temperature, over-current and under-voltage protection, as well as an adjustable switching frequency. Additionally, the MPM3805GQB-18-P features automatic fault recovery and power sequencing and gating.

The MPM3805GQB-18-P works by taking an input voltage power source and converting it into an output voltage that can be used to power an electrical load. It uses a switching topology which enables it to convert the input voltage into pulses of current which are then converted to an output voltage. This process is known as pulse width modulation (PWM).

The MPM3805GQB-18-P contains a number of power components that help control and maintain the output voltage. This includes an input voltage regulator, which is responsible for maintaining the input voltage within a specified range. Additionally, it contains an output voltage regulator, which is also used to ensure that the output voltage does not exceed the required level.

The MPM3805GQB-18-P also contains an oscillator, which is used to control the frequency of the pulses of current that are being output from the converter. This ensures that the output voltage remains within the predetermined voltage range. Lastly, there is a MOSFET switch which is used to transfer the pulses of current from the input voltage regulator to the output voltage regulator.

The MPM3805GQB-18-P is an ideal choice for DC-DC converters in IBA applications. It enables system designers to reduce the space requirements for their thermal solutions, and it is capable of providing a wide variety of output voltage levels for different applications. It also offers a number of advanced safety features, such as programmable over-voltage, over-temperature, over-current and under-voltage protection.
