LM5013-Q1EVM User's Guide
The LM5013-Q1EVM has a 100-V DC/DC buck regulator that employs asynchronous rectification and achieves
high conversion efficiency. The EVM operates over a wide input voltage range of 15-V to 100-V to provide a
regulated 12-V output at 300-kHz switching frequency. The module design uses the LM5013-Q1 asynchronous
buck converter with wide input voltage (wide V
MOSFET, cycle-by-cycle overcurrent protection, and precision enable. With AEC-Q100 grade 1 automotive
qualification, the LM5013-Q1 is rated to operate over a junction temperature range of -40°C to +150°C. The
LM5013-Q1 is available in an 8-pin SO PowerPAD
DC/DC solutions.
