System architects can rapidly comply to international electrotechnical commission (IEC) and safety integrated level (SIL) standards to achieve long-term system reliability with the MAX17572 and MAX17574 Himalaya synchronous step-down DC-DC converters from Maxim Integrated Products.
The industrial market is digitising at a rapid pace, all while continually improving the safety, performance and intelligence of systems. Tasked with deploying processors from sensors to control units, designers must reduce power dissipation while managing space constraints. They are also hard-pressed with thermal challenges and meeting safety standard regulations – critical to robust long-term reliability, yet very time consuming. In addition, designers must account for high-voltage transients up to 60 V on a 24 V or 48 V bus.
With the MAX17572 and MAX17574, designers can operate 4,5-60 V as well as reduce power dissipation and solution size compared to other solutions to comply with the IEC 61508 safety standard. The converters guarantee 1 A and 3 A operation (5 V 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 backup, Power-over-Ethernet (PoE) and data centres.
Operating over the -40°C to +125°C temperature range, the MAX17572 is available in a 12-pin, 3 x 3 mm thin-DFN (TDFN) package and the MAX17574 is available in a 24-pin, 4 x 5 mm TQFN package
