TheAOZ1977-1isahigh-efficiencyLEDdrivercontrollerforhighvoltageLEDbacklightingapplications
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°
