DC/DC inverting converters shrink automation form factor and energy budget

Two integrated synchronous DC/DC converters, the MAX17577 and MAX17578, halve component count and reduce energy loss for industrial automation and signal conditioning applications.

The MAX17577 and MAX17578 integrated level-shifters reduce board space requirements by 72 per cent, reduce energy loss by 35 per cent and improve voltage transient protection, says Maxim Integrated. They are also claimed to have the industry’s widest input voltage range of 4.5 to 60V.

“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.”

The small, high-efficiency synchronous inverting DC/DC step-down converters are Maxim’s first 60V inverting DC/DC converters with integrated level shifters. As a result, they save board space, halving component count, and use 35 per cent less energy than the closest competing solutions, says the company. Both ICs reduce size, heat, and cost, while simplifying the design of negative output voltage rails needed for analogue signals in intelligent IoT devices used in factory automation, building automation and communications systems.

The MAX17577 and MAX17578 integrate level shifting circuitry to reduce component count, and therefore cost, while reducing component area to 60 mm². These reductions address the need for network edge devices to incorporate artificial intelligence (AI) capabilities without increases in size or heat generation, explained Maxim. These synchronous inverting converters protect against input voltage transients with what is believed to be the industry’s widest input voltage range (4.5 to 60V), thus increasing system robustness in harsh environments.

The MAX17577 and MAX17578 generate less heat by dissipating 35 per cent less power than competitive solutions. This improves system reliability and provides developers with up to six percentage points more efficiency.

The MAX17577 and MAX17578 are available now, together with the MAX17577EVKIT# and MAX17578EVKIT# evaluation kits.
