The MAX750ACSA is a monolithic, high-efficiency, low-power DC-DC switching regulator ideal for creating a reliable, well-regulated power supply using a small form factor. It integrates a power switch, a highly efficient Boost/Inverted Buck-Boost regulator, and controllers with synchronous rectification to deliver up to 800mA output current with a low power loss of up to 1.2 W.

The MAX750ACSA is uniquely designed to operate from a wide input voltage range of 1.8V to 6V and can precisely regulate a wide output voltage range of 0V to 6V. The IC is optimized for a wide operating temperature range of -40°C to +85°C and is certified to the stringent automotive AEC-Q100 Quality Standard. Additionally, it also offers a wide input range undervoltage lockout, programmable output voltage, overcurrent protection, soft start, and thermal shutdown for optimal system performance.

The MAX750ACSA is suitable for many applications, including automotive automotive systems and consumer electronics applications, such as power adapters, remote and portable equipment, digital cameras, and cell phones. Its low power consumption and small form factor makes it an ideal solution for these types of applications.

DC-DC Switching Regulator Application Field and Working Principle

A DC-DC switching regulator is an electronic circuit that uses switching, typically on a transistor, to convert a DC voltage with a constant input voltage to a DC voltage of variable, but regulated output voltage. The output voltage is regulated to a specific value through feedback, typically through either a voltage divider, an optocoupler, or a sensor. The operation principle of a DC-DC switching regulator is the same as that of a variable output voltage regulator, however, the switching regulator has a much higher efficiency than a linear regulator, typically 95% or more.

The MAX750ACSA is a monolithic, high-efficiency, low-power DC-DC switching regulator ideal for creating a reliable, well-regulated power supply. Its integrated power switch and highly efficient Boost/Inverted Buck-Boost regulator make it an excellent choice for many applications, including automotive systems and consumer electronics. Additionally, its wide input voltage range, programmable output voltage, overcurrent protection, soft start, and thermal shutdown features make it an ideal power sourcing solution.
