The MAX17577 and MAX17578 from Maxim Integrated Products Inc. are the industry’s smallest, highest-efficiency synchronous inverting DC-DC step-down converters.

The MAX17577 and MAX17578 from Maxim Integrated Products Inc. are the industry’s smallest, highest-efficiency synchronous inverting DC/DC step-down converters. Rated at 60V, the inverting DC/DC converters have integrated level shifters and save up to 72% of board space by reducing component count by half while using 35% less energy than the closest competitive solutions. 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 (AI) capabilities, designers must reduce the solution size and heat generation. The MAX17577 and MAX17578 integrate level shifting circuitry to reduce component cost and count by as much as 50% while reducing component area to 60mm2. 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 generate less heat by dissipating 35% less power than competitive solutions, improve system reliability and provide developers with up to six percentage points more efficiency.

“By integrating level shifters, the MAX17577 and MAX17578 reduces design size and component count dramatically for baseband solutions and IoT devices,” said John Woodward, business management director, Industrial Power Product Line at Maxim Integrated. “These efficient negative voltage regulators reduce system temperature rise and support the industry’s widest input voltage range to provide robust protection against unpredictable voltage transients.”
