The APE1612-3 uses current mode, 1.2 MHz fixed frequency architecture to regulate the LED current, which is set using an external current sense resistor.
The APE1612-3 features a low 300 mV feedback voltage that reduces power loss and improves efficiency. The OV pin monitors the output voltage and turns off the converter if an over-voltage condition is present due to an open circuit condition. The APE1612-3 includes under-voltage lockout, current limiting and thermal shutdown protection preventing damage from an output overload.
The APE1612TY-HF-3 is shipped in a small RoHS/REACH-compliant TSOT-26 package.
