The LM5169P evaluation module (EVM) is a 115V DC/DC buck regulator that employs synchronous rectification to achieve high conversion efficiency in a small footprint. The EVM operates over a wide input voltage range of 20V to 115V to provide a regulated 12V output at up to 0.650A with a 500kHz switching frequency. The output voltage has better than 1.5% set-point accuracy and is adjustable using an external resistor divider. The module design uses the LM5169PNGUR synchronous buck converter with wide input voltage range, wide duty-cycle range, integrated high-side and low-side power MOSFETs, advanced overcurrent protection and precision enable.
