1. LM5140 Dropout Data VIN=8V, VOUT =8V
Do not distribute

2. LM5140 VIN=12V, VOUT =8V, 5.5A Load, SYNIN 460kHz
The EVM was set-up to output with a SYNCIN frequency of 460kHz

3. LM5140 Dropout Data VIN=8V, VOUT =8V, 5.5A Load
As VIN is lowered and the LM5140 reaches it minimum off time, it will drop the oscillator frequency to keep the output in regulation. It will ignore the SYNCIN signal, for more information refer to section in the data sheet.

The LM5140 oscillator frequency drops to 55kHz when VIN is 8V with a 5.5A load on the output.
