Maxim Integrated MAX17577 and MAX17578 synchronous DC-DC inverting converters

The MAX17577 and MAX17578, from Maxim Integrated Products, are small, high-efficiency synchronous inverting DC-DC step-down converters. As 60 V inverting DC-DC converters with integrated level shifters, the devices are claimed to save up to 72% of board space by reducing component count by half while using 35% less energy than competitor solutions. Both ICs are said to reduce size and heat 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. The converters integrate level shifting circuitry to reduce component cost and count by as much as 50% while reducing component area to 60 mm². The synchronous inverting converters protect against input voltage transients with a wide input voltage range from 4.5 to 60 V, thus increasing system robustness in harsh environments.
