The AOZ1977-1 is a high-efficiency LED driver controller for high voltage LED backlighting applications. It is designed to drive high-brightness LED light bar in LED TV applications. The AOZ1977-1 can support a wide range of input and output voltages. The input bias voltage of AOZ1977-1 is from 8V to 30V.The AOZ1977-1 has multiple features 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 AOZ1977-1 is available in a standard SO-16 package and operates over the temperature range of -40°C to +85°.
