Working Principle

The MMPF0200NPAEP is a wide-range adjustable power solution that provides excellent power efficiency and low EMI levels by microprocessor-based power regulation. It uses a unique technology platform that can create multiple positive and negative operating voltages with on-board sequencing and control. The solution utilizes one internal controller, two buck regulators, one buck-boost regulator, and one converter voltage feedback, as well as current limit and thermal protection functions.

The MMPF0200NPAEP has five constructed buck converters with a maximum PWM modulation frequency of 1.2 MHz. Buck-Boost regulators have a maximum output current of 30A, 160mA, and 400mA for each buck regulator. The output voltage for the buck-boost regulators is adjustable between 0.6V and 6V, and the on-time for the buck regulator can be adjusted from 0.65μs to 16μs. Other features include integrated soft-start, voltage and current monitoring, output voltage fading and adjustable load-line and over-current protection.

The MMPF0200NPAEP also provides an integrated feedback and clamping section to ensure system stability and protect the buck-boost regulator from excessive current. The integrated feedback system also helps in reducing peak current transients, providing low EMI mask compliance.

The MMPF0200NPAEP is a low-power, high-efficiency, and low-noise solution, optimized for a variety of applications. It is compliant with multiple environmental standards and requirements and is suitable for use in a wide range of signal conditioning applications.
