Integrated synchronous DC-DC inverting converters

Maxim Integrated has launched the MAX17577 and MAX17578, said to be 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 board space by reducing component count and use less energy than their nearest competitor 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 capabilities, designers need to 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 percent while reducing component area to 60 mm². 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 percent less power than competitive solutions, improve system reliability and provide developers with up to six percentage points more efficiency.

Key Advantages

  • Cuts Component Count: Cuts component count to 50 percent and reduces design size by 72 percent
  • Highest Efficiency: Six percentage points higher efficiency, dissipates 35 percent less energy than closest competition
  • Widest Range: 4.5V to 60V is the industry’s widest input voltage range
