The MAX1921EUT33+T is an integrated high-frequency, dual-channel DC-DC switching regulator. It is a Pulse Width Modulated (PWM) microcontroller with two key features: a high switching frequency and current-limited control. It is designed to convert unregulated DC from sources such as batteries, AC adapters and solar panels into regulated voltages, providing optimized power and efficiency for power consumption-critical applications. The MAX1921EUT33+T is a versatile regulator, suitable for high-performance DC-DC step-down and step-up applications.

The high switching frequency of the MAX1921EUT33+T eliminates large filter components, requires minimal board space and simplifies circuit layout, making it the perfect choice for small, heat-sensitive systems. The current-limited control reduces the potential of power supply oversizing, thus improving reliability and reducing system costs. Due to its high switching speed, flexible control options, and a wide input voltage range, the MAX1921EUT33+T can be used in a variety of applications, such as LED lighting, mobile appliances, and power supplies.

The MAX1921EUT33+T has a default switching frequency of 2.5MHz and provides a wide input voltage range of 4.5V to 28V. The output voltage can be adjusted in the range of 0.8V to 20V, making it an ideal choice for efficient power conversion in industrial, automotive, and communication applications. The high switching frequency reduces the size of external components and allows for more flexibility in setting the parameters of the regulator during the design stage.

The MAX1921EUT33+T features an adjustable current limit function which limits the maximum current that can be drawn from the input source. This feature prevents possible damage from an over-current situation and reduces chances of thermal runaway due to excessive heat. The adjustable current limit also reduces the need for additional current limiting circuits, thus lowering system costs.

The MAX1921EUT33+T is a highly efficient DC-DC switching regulator that can be used in a variety of applications. It provides excellent power savings, can be easily integrated into small designs, and is suitable for both step-up and step-down applications. The current-limited control protected from overloads and makes it a reliable choice for power supplies with stringent requirements.
