Wide VIN Power Solutions

  • Increased protection against input transients
  • High power density with large conversion ratios
  • Scalability to fit a wide variety of applications

Applications that benefit from a wide input voltage range power supply

Numerous end equipment within the automotive, industrial, and communications segments are subjected to rugged environments that dictate the use of a power supply with wide input voltage capability. Many systems face unregulated input voltages with unpredictable transients, and a wide VIN power supply helps to protect the load while reducing the cost of protection circuitry. Some systems simply require conversion from a high voltage to the point-of-load in the smallest board area possible. And then there are designers that create a variety of systems with various input voltages that leverage a wide input voltage in order to benefit from economies of scale and design reuse.

Browse the markets and end equipment below for suggested products and reference designs that will allow you to benefit from the flexibility provided by a wide VIN power supply.

Featured Applications


Whether you are designing for 12 V or 24 V automotive, transient protection from load dump and cold crank are constant concerns in your power supply design. AEC-Q100 qualified wide VIN devices help to protect the load while reducing system protection complexity and cost.


Communications Infrastructure

While wide VIN devices are common in telecom due to system voltage transients, other end equipment such as Ethernet switches benefit from the power density provided by TI’s wide input voltage portfolio.



Even though many industrial systems feature a nominal 24 V input bus, that 24 V is often unregulated. This means input voltage transients up to 42 V, 60 V, and even 100 V are common, and a power supply with wide input voltage capability is desirable.
