[Power Supply Design Proposal Example] Ultra-wide range support for input DC 24V to 110V.

By eliminating the switch, it is possible to achieve stable output! Reliability has also improved!

We received a request from a customer to develop a power supply with an ultra-wide input voltage range of 12 to 110V. Typically, when the range is wide, it is necessary to separate the power supply by input voltage, such as 12 to 24V or 48 to 72V, or to use a switch to toggle between them. By using a buck-boost switching converter that can automatically switch between boost and buck operations, we can accommodate an ultra-wide input range of DC 24V to 110V. Eliminating the switch allows for stable output and improves reliability. [Challenges] ■ Development of a power supply with an ultra-wide input voltage range of 12 to 110V ■ When the range is wide - It is necessary to separate the power supply by input voltage, such as 12 to 24V or 48 to 72V - Or it is necessary to use a switch to toggle between them *For more details, please refer to the related link page or feel free to contact us.
