The MAX17577 and MAX17578 from Maxim Integrated Products, Inc. (NASDAQ: MXIM) 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. 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. 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 60 mm2, 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 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

Commentary
“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.”
