Synchronous Inverting Converters Shrink Board Space

Maxim Integrated has introduced the MAX17577 and MAX17578 which the company claims are the industry’s smallest, highest-efficiency synchronous inverting DC-DC step-down converters. As Maxim’s first 60V inverting DC-DC converters with integrated level shifters, these devices save up to 72 percent of board space by reducing component count by half while using 35 percent less energy than the closest competitive solutions, says Maxim. Both ICs reduce size, heat and cost, while simplifying the design of negative output voltage rails needed for analog signals within intelligent IoT devices found in factory automation, building automation and communications systems.

As network edge devices expand with Artificial Intelligence capabilities, designers must reduce the solution size and heat generation, says Maxim. They seek solutions that are more efficient, creating less heat and use less board space, saving time and cost. The MAX17577 and MAX17578 integrate level shifting circuitry to reduce component cost and count by as much as 50 percent while reducing component area to 60mm2, a 72 percent advantage in board space over competitive solutions. These synchronous inverting converters protect against input voltage transients with the industry’s widest input voltage range from 4.5V to 60V, thus increasing system robustness in harsh environments.

The MAX17577 and MAX17578 and available at Maxim Integrated’s website for $1.63 (1000-up, FOB USA); also available from authorized distributors. Evaluation kits are available for each chip for $29.73

The MAX17578EVKIT# evaluation kit is available for $29.73 EE-Sim models are available.
