With a 40-V rated integrated switch FET, the OCP8178A is a boost converter that drives LEDs in series.
The boost converter runs at 600kHz fixed switching frequency to reduce output ripple, improve conversion efficiency, and allows for the use of small external ponents.
The default white LED current is set with the external sensor resistor Rset, and the feedback voltage is regulated to 200mV, as shown in the typical application.
