The LM38020EVM is an 80-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 6 V to 80 V to provide a regulated 5-V output at 400-kHz switching frequency. The output voltage has better than 1.5% setpoint accuracy and is adjustable using an external resistor divider. The module design uses the LMR38020F synchronous buck converter with the following:
The LMR38020 converter is available in an 8-pin SO PowerPAD™ integrated circuit package to enable high-density, low-component count DC/DC solutions. The LMR38020EVM evaluation module is qualified for the LMR38020 as well as the LMR38020-Q1 buck converter. See Table 1-1 for package information.
