CH1 Short Circuit
OTP triggered
Boost converter and channels are shut down until V IN is cycled

CH1 Open Circuit with OTP not triggered, CH1 < 8V V OUT will ramp to OVP. CH1 will
infinite resistance time-out after 190ms and switch
off. V OUT will then reduce to
normal level

Any channel that is below the target current will time-out after 190ms Highest LED string
while V OUT is regulated at V OVP , and V OUT will then return to the V F of CH1 - CH4
