Gain down disable. Setting this option does not allow the charge pump to switch to lower gains. NOT AVAILABLE on ADP8860 1 = the charge pump doesn't switch down in gain until all LEDs are 0. The charge pump switches up in gain as needed. This feature is useful if the ADP8863 charge pump is used to drive an external load. This feature must be used when utilizing small fly capacitors (0402 or smaller). 0 = the charge pump automatically switches up and down in gain. This provides optimal efficiency, but is not suitable for driving loads that are not connected through the ADP8863 diode drivers. Additionally, the charge pump fly capacitors should be low ESR and sized 0603 or greater.
