LM5150RUMHDEVM EVM User’s Guide
The LM5150RUMHDEVM evaluation module (EVM) is designed to supply a minimum voltage from a
vehicle battery during cranking and demonstrate a high density layout design example using the LM5150
Wide VIN Automotive Low I
Q
Boost Controller IC. The EVM requires minimum 5V at the output to start up
properly. After the start-up, the input voltage can go down to 3.2V and can go up to 40V. The EVM
produces minimum 6.8V at load current up to 1.1A (continuous) 2.2A (peak). When the input/output
voltage is high enough to guarantee minimum 6.8V at the output, the device automatically goes into low I
Q
standby mode.

1 Features and Electrical Performance
• 3.2V to 40V input voltage range (5V is required at the output to start up. 6V input is sufficient to make
the output voltage greater than 5V)
• 6.8V target output voltage when input voltage drops below the target.
