Figure 4. PWM Dimming Curve of AL5816 The AL5815 and AL5816 have internal Over Temperature Protection (OTP). When the junct ion temperature is over +160° C, the IC will shut down . A power cycle off and on or the junction temperature dropping by +30°C will make the IC turn back on. and/or use a better PCB layout. The device has internal compensation and therefore there’s no need to have any components in the feedback loop.
