AOZ1977 High Voltage LED Driver IC

The AOZ1977 is a high-efficiency LED driver controller for high voltage LED backlighting applications. It is designed to drive a high-brightness LED light bar in LED TV applications. The AOZ1977 can support a wide range of input and output voltages. The input bias voltage of the AOZ1977 is from 8 V .

AOZ1977 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 an
