LP8758EVM: How are mode and multiphase status determined in the EVM GUI?

Jason Teeter

Part Number: LP8758EVM
Other Parts Discussed in Thread: LP8758

The LP8758 EVM user guide shows that the mode (PFM, sleeping, etc) and multiphase status (master, slave) of each buck are indicated in the GUI. I do not see any reference to this information in the LP8758 register descriptions. How does the GUI access this information (and thus how would I access it in my application)?

Hi Jason,

Those buck mode and multiphase status information are for reference and testing of the device on EVM only. They are not intended to be used in real application.
To emulate same kind of information about buck status you can read averaged load current and deduce buck status depending on a current level.
