5 FAQs about [Outdoor power supply design requirements]

How to design a power supply?

Table 7: Boost Reference Design. Designing a power supply requires knowledge of the appropriate topology for the given application. Having chosen a topology, it must then be customized for an input voltage range, output voltage, and current drive as required. This can be a time-consuming procedure for the novice and experienced designer alike.

How do I speed up the design cycle for a power supply?

To speed up the design cycle for this type of power supply, several proven power-supply reference designs are available (typically with > 90% efficiency). These use the MAX17690 60V, no-opto isolated flyback controller, for a variety of different input voltage ranges and output voltages and power requirements (Table 1).

What is the maximum operating voltage for industrial equipment?

However, the maximum operating voltage for industrial applications is expected to be 36V to 40V for non-critical equipment. Meanwhile, critical equipment in industrial applications, such as controllers, actuators, and safety modules, must support 60V (IEC 61131-2, 60664-1, and 61508 SIL standards).

What is a boost topology power supply?

A “boost” topology power supply is ideal for this application. The MAXREFDES1018 power-supply reference design (shown in Table 7) uses a boost topology to produce a 13.5V output (with 6mA current drive) from an input voltage range of 1V to 3.3V.

Why do building control systems need a wide-input range DC-DC voltage converter?

Building control systems, including some industrial use cases like smart building, management, interior comfort and air quality management, field devices, and actuators, utilize a rectified 24AC input voltage further justifying the need for wide-input range DC-DC voltage converters.
