Power Management Integrated Circuits (PMICs) are utilized for the purpose of providing power to many types of electronic components such as microcontrollers, FPGAs, processors and embedded systems such as Arduino. Voltage Regulators are important components of PMICs, and they are used to provide auxiliary power and control power levels in a power circuit. A DC DC Switching Regulator is a specific type of Voltage Regulator that takes a direct current supply and converts it to a different desired DC voltage or current. The MAX751CPA+ is an example of a reliable DC DC Switching Regulator that is widely used in many applications.

Application Field

The MAX751CPA+ is designed to convert a wide range of DC voltages from 3.0V to 8.0V input to any desired regulated output, with output voltages ranging from 0.8V to 6.0V. This makes it versatile for many different types of projects and applications, such as those requiring battery-powered devices supplied with stable voltage for optimal performance and longevity. It can provide output currents of up to 5.5A, and is capable of driving loads up to 150mA over a wide output range of voltages. Besides its use in battery-powered applications, the MAX751CPA+ is also useful in solar-powered, automotive and mobile devices.

The MAX751CPA+ is optimized for high efficiency, preserving battery life and minimizing power loss. It is also equipped with a variety of features such as protection against input over-voltage, over-current and over-temperature, output under-voltage, over-current and over-temperature protection, and thermal shutdown which further increased its reliability and safety ratings in a wide range of applications. The MAX751CPA+ also has soft-start functionality and is available in a thermally-enhanced 3mm x 5mm TQFN-16.

Working Principle

The MAX751CPA+ operates on a simplified Buck topology and is powered from an input voltage source, such as a battery. It converts the unregulated input voltage (Vi) from a battery to a regulated output voltage (Vo) by switching the input voltage into short pulses, which drives a high frequency transformer. The transformer is used to step up or step down the voltage to the desired output voltage, and it is also used to store energy in its magnetic field. The transformer provides an isolated output voltage, as the input voltage and the output voltage remain completely isolated from each other.

The MAX751CPA+ features a 0.2Ω integrated high-side N-MOSFET with a current limit of 5.5A and thermal shutdown at 150°C. This allows for improved power dissipation, increased efficiency and better power control. The switching frequency of the regulator can be externally set from 200kHz to 1.2MHz. A programmable soft-start feature can also be triggered by the user through an external capacitor, which allows for a slower startup of the output voltage ramp-up. Finally, the MAX751CPA+ has a logic-controlled enable pin to facilitate operations, configured to enable ON/OFF action with a high or low level input.

The MAX751CPA+ is a reliable and efficient DC DC Switching Regulator that can offer a wide range of features and benefits for different applications. It is capable of delivering stable and regulated output power, while also providing protections against possible damage. With its optimized design, robust features and high reliability rating, the MAX751CPA+ is an ideal choice for many types of power circuits.
