Principio de funcionamiento

The OTK5272S uses a step-down (buck) converter topology with integrated power MOSFET rated for 60V. The output current is set by an external sense resistor. PWM dimming controls brightness by enabling/disabling the output at up to 20kHz. Analog dimming adjusts the internal reference voltage. The control loop maintains constant current through the LED string. Open LED protection shuts down the converter when the output voltage exceeds the threshold. Short LED protection limits current when output is shorted.
