The Himalaya DC-DC synchronous buck converter from Maxim Integrated Products, Inc. provides a 40% reduction in power dissipation and reduces the solution size by 50% compared to other competing products.
The industrial market is digitizing rapidly, all while continuously improving the safety, performance, and intelligence of systems. Those responsible for implementing processors—from sensors to control units—and the designers must reduce power dissipation while managing space constraints. They are also pressured by thermal issues and must comply with standard safety regulations, which are critical for robust long-term reliability but also time-consuming. Furthermore, designers must account for high-voltage transients of up to 60V on a 24V or 48V bus.
With MAXIM's MAX17572 and MAX17574 DC-DC converters, designers can operate with 4.5 to 60V, while also reducing power dissipation and solution size compared to other solutions, quickly achieving compliance with the IEC 61508 safety standard. The converters guarantee operation at 1A and 3A (5V output) and are ideal for high-voltage industrial applications such as sensors, programmable logic controllers (PLCs), industrial controls, distributed power supply regulation, and factory/building/grid automation. They are also applicable to battery backup, Power-over-Ethernet (PoE), and data centers. Operating in the temperature range of -40ºC to +125ºC, the MAX17572 is available in a 12-pin, 3mm x 3mm DFN (TDFN) package and the MAX17574 is available in a 24-pin, 4mm x 5mm TQFN package.
Key Advantages
• High Efficiency: Provides >90% efficiency across 50-100% of load current
• Small Solution Size: Integrated MOSFETs and compensation reduce solution size; operates at high switching frequency with minimal turn-on time
• Ease of Use: Internal compensation responds to any combination of switching frequency and output voltage without compromising bandwidth for fast design.
