Texas Instruments LM5164-Q1 EVM User Manual

The LM5164-Q1 EVM
high conversion efficiency in a small footprint. 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 output voltage has better
than 1.5% setpoint accuracy and is adjustable using an external resistor divider. The module design uses
the LM5164-Q1 synchronous buck converter with wide input voltage (wide V
range, integrated high-side and low-side power MOSFETs, cycle-by-cycle overcurrent protection, and
precision enable. With AEC-Q100 grade 1 automotive qualification, the LM5164-Q1 is rated to operate
over a junction temperature range of –40°C to +150°C. The LM5164-Q1 is available in an 8-pin SO
PowerPAD™ package to enable high density, low component count DC/DC solutions. The LM5164-
Q1EVM-041 evaluation module is qualified for the LM5164 as well as the LM5164-Q1 buck converter. See
Table 1 for package information.
