LM5158EVM-BST Evaluation Module
The LM5158EVM-BST evaluation module showcases the features and performance of the LM5158 device
as a wide input voltage, non-synchronous boost converter with dual random spread spectrum. The standard
configuration is designed to provide regulate a 12-V output at 1.2 A from an input of 3.3 V to 9 V (load derated by
half from < 6-V input), and switching at a frequency of 2.1 MHz.
