Wide VIN power solutions

Increased power density and reliability for systems requiring maximum operating voltages ≥ 30V

Applications that benefit from a wide input voltage range power supply

Automotive, industrial and communications systems are commonly fed with unregulated input voltages and 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. Other times, designers may desire one wide input voltage device that can be used in a variety of different applications, permitting economies of scale and facilitating design reuse.  

Browse the markets and end equipment below to find examples of flexible wide VIN devices that each provide this entire array of benefits. 

Automotive

Whether you are designing for 12V or 24V 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.

Industrial

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