Maxim MAX17572 and MAX17574 Himalaya step-down DC-DC converters

System architects can now rapidly comply to international electrotechnical commission (IEC) and safety integrated level (SIL) standards with the MAX17572 and MAX17574 Himalaya synchronous step-down DC-DC converters from Maxim Integrated Products. The highly efficient converters provide a 40% reduction in power dissipation and shrink solution size by 50% compared to other solutions, according to the company.

With the DC-DC converters, designers can operate 4.5 to 60 V, as well as reduce power dissipation and solution size, to comply with the IEC 61508 safety standard. The converters ensure 1 and 3 A operation (5 V output) and are suitable 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 centres.

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