The AOZ1977-1 is a high-efficiency LED driver controller for high voltage LED backlighting applications.

to protect the regulator under fault conditions. A control pin can disable an external switch to disconnect the LEDs current path from the output in PWM dimming or under catastrophic failure conditions. Cycle-by-cycle current protection limits the peak inductor current. Thermal shutdown provides another level of protection. Low feedback voltage (500mV) helps reduce power loss. The AOZ1977-1 features sync function to allow for synchronization with external clock or multiple AOZ1977-1. The AOZ1977.
