• Automatic Skip Cycle mode

LP5910YKA18EVM Working Principle

The LP5910YKA18EVM employs a buck converter topology, which uses a power MOSFET switch to regulate the output voltage. A buck converter works by controlling the duty cycle of the power switch such that when it is turned on, the voltage at the output is higher than that at the input, and when it is turned off, the voltage at the output is less than that at the input. This difference is converted into a regulated output voltage. The regulator offers a number of protections which are designed to protect the device from overloads and other potential faults such as:

• Over-Voltage Protection
• Under-Voltage Lockout
• Over-Temperature Protection
• Load Regulation

The LP5910YKA18EVM also has an Application Note which provides setup and configuration information, as well as detailed circuit examples to help users get their applications up and running quickly and easily. This document is available on the LP5910YKA18EVM webpage.

Conclusion

The LP5910YKA18EVM is a versatile Linear Voltage Regulator Evaluation Module with features and protection specifically tailored to automotive, industrial and medical applications. It is a robust, easy to use solution that offers a maximum 10A output current, and is capable of supporting input voltages from 4.5V to 36V. The on-board protection features and support documentation make the LP5910YKA18EVM a great choice for applications requiring a regulated power supply.
