The APE1612-3 features a low 300mV 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. APEC says that its small size and high efficiency suit the APE1612-3 to backlighting applications. A wide 200Hz to 200kHz range enables the device to be used in PWM dimming. It comes in a TSOT-26 package.
