The LM5156EVM-BST evaluation module showcases the features and performance of the LM5156
device, wide input voltage, non-synchronous boost controller. The standard configuration is designed to
provide a regulate output of 12 V at 36 W from a minimum input of 4 V, switching at a frequency of 440
kHz, withstanding voltage transients from 3 V to 42 V. The module is designed for ease of configuration,
enabling a user to evaluate different applications on the same module. Functionality includes dual random
spread spectrum (DRSS), external clock synchronization, programmable slope compensation, adjustable
soft-start, programmable cycle-by-cycle current limit, and output over voltage protection.
