Internal Low-Side Switch in LED5000?

What’s the purpose of the internal low-side switch in LED5000? Is it a synchronous converter? If so, also why is an external Schottky shown in the application diagrams?

    Yes, it works in synchronous mode.

    still, after the low-side FET has been switched off, there’s always a specific dead time while the inductor still drives current. That current would flow through the body diode of the low-side FET, reducing effectiveness and increasing the radiated noise. This behavior can be improved by using a Schottky that takes over the current during the dead time.

    In setup to perform floating point operations with library calls, you should add-mfloat-abi = soft. Please refer to-mfloat-abi = name on https//gcc.gnu.org/onlinedocs/gcc-4.4.7/gcc/ARM-Options.html

    In setup to apply functions printf and scanf functions, you should add these 2 linker options

    Hope it helps

    Yes, LDOs 3,4,7,8 and 11 can be set to bypass mode by setting LDO<x>_BYP register to (1) and by setting LDO<x>_AUTO to (1). In sequencing they follow LDO<x> _STEP timing. Please note: Voltage monitoring function cannot be used for any LDO in bypass mode.

    Code-flash would have to be addressed as "far" data memory, I might recommend using the IAR compiler as it handles the "huge" memory qualifier that allows "far" array accesses across 64KB boundaries.  Or you could use CC-RL with a simple assembly routine to handle the "huge" memory references.
