The LM5168P evaluation module (EVM) is a 115 V 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 20 V to 115 V (120 V absolute maximum) to provide a regulated 12 V output at up to 0.3 A with a 500 kHz 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 LM5168P synchronous buck converter with wide input voltage range, wide duty-cycle range, integrated high-side and low-side power MOSFETs, advanced over-current protection and precision enable.
