Maxim’s Himalaya Step-Down DC-DC Converters Enable Rapid Compliance of Safety Standards for Industrial Applications

Maxim Integrated Products MAX17572 and MAX17574 reduce power dissipation by 40% and solution size by 50% 

Maxim Integrated Products’ new MAX17572 and MAX17574 Himalaya synchronous step-down DC-DC converters enable system architects to rapidly comply with international electrotechnical commission (IEC) and safety integrated level (SIL) standards.

Helping achieve long-term system reliability, the new converters touts to provide a 40% reduction in power dissipation and shrink solution size by 50% compared to other solutions.

Key Advantages

  • High Efficiency: Delivers >90% efficiency across 50-100% of the load current
  • Small Solution Size: Integrated MOSFETs and compensation reduce solution size; Operates at high-switching frequency with low minimum on-time
  • Ease of Use: Internal compensation addresses any output voltage and switching frequency combination without compromising bandwidth for rapid design

With Maxim’s MAX17572 and MAX17574 DC-DC converters, designers can operate 4.5-60V as well as reduce power dissipation and solution size compared to other solutions to rapidly comply with the IEC 61508 safety standard.

Applications

The converters guarantee 1A and 3A operation (5V output) and are ideal for high voltage industrial applications such as sensors, programmable logic controllers (PLCs), industrial controls, distributed supply regulation, and factory/building/power grid automation. They are also applicable for battery back-up, Power-over-Ethernet (PoE), and data centers.

“Industrial equipment’s control power supply inputs must meet 60V input and low thermal dissipation for reliable operation and standards compliance,” said Andreas Kuhn, Head of Hardware Development, Drives Chemnitz, Siemens AG. “With Maxim’s Himalaya DC-DC converters, we can consistently meet our requirements for the SINAMICS Drives Family.”

“Maxim was the first to bring synchronous rectification at 60V to the market,” said Viral Vaidya, Executive Business Manager at Maxim Integrated. “Today, we continue this innovative approach by delivering 40% lower dissipation even against competing synchronous solutions.”

Packaging

Operating over the -40-degree Celsius to +125-degree Celsius temperature range, the MAX17572 is available in a 12-pin, 3mm x 3mm thin-DFN (TDFN) package and the MAX17574 is available in a 24-pin, 4mm X 5mm TQFN package.
