Maxim Integrated MAX5092AATE+T Dual-Output, Buck Controller

The MAX5092AATE+T from Maxim Integrated is a high-performance, dual-output, synchronous buck controller designed to deliver efficient power management and regulation for a variety of applications. This compact and robust integrated circuit (IC) is engineered to provide precise voltage regulation, while maintaining high efficiency and reliability in a small footprint, making it ideal for space-constrained environments.

The MAX5092AATE+T operates over a wide input voltage range from 5.5V to 23V, making it suitable for use in systems powered by multi-cell batteries or regulated 5V and 12V power rails. Its dual outputs can be configured for 5V/3.3V or adjustable output voltages, providing design flexibility for different application requirements. The adjustable switching frequency, which can be set from 300kHz to 2.2MHz via an external resistor, allows designers to optimize the trade-off between efficiency and external component size.

With integrated high-side and low-side MOSFET drivers, the MAX5092AATE+T minimizes external component count, reducing both system complexity and cost. Its high-side bootstrap diode further simplifies the design by eliminating the need for an external diode. The device also features cycle-by-cycle current limit, thermal shutdown, and under-voltage lockout for robust protection against fault conditions.

Maxim Integrated's MAX5092AATE+T is available in a thermally efficient, 16-pin TQFN package with an exposed pad, ensuring excellent thermal performance and ease of heat dissipation. This makes it an excellent choice for high-density power applications where maintaining a low junction temperature is critical for system reliability.

Applications that can benefit from the MAX5092AATE+T include distributed power systems, industrial controls, automotive infotainment and telematics, and other systems requiring multiple regulated power rails. With its precision voltage regulation, flexibility, and protection features, the MAX5092AATE+T is an ideal solution for designers seeking a reliable, high-performance power management solution.
