AOZ1948 Single Channel LED Driver IC General Description The AOZ1948 is a high-efficiency Buck controller for general purpose high voltage and low voltage LED backlight applications. It does not require a separate dimming MOSFET. It utilizes fixed off time control and operates using average current control feedback, features internal compensated reference and no external compensation is required Low feedback voltage (0.6V) helps reduce power loss. The AOZ1948 features selectable Off Time control to allow for wide range of applications, and auto-restart OCP/short-circuit protection. The AOZ1948 is available in a standard SO-8 package and operates over the temperature range of -40°C to +85°C.
