[1] It is not recommended to operate the device at the supply boundaries unless the supply is regulated well.
[2] Clip control on results in smooth clipping.
[3] Clip control off results in maximum output power.
[4] The efficiency of the total application is slightly worse due to the power dissipation in LDO and DCDC
converter.
