Overview
AOZ1977 High Voltage LED Driver IC General Description 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 to 30 V.
The AOZ1977 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 an a...
