White LED Driver for 4Ch Large LCD Panels (DC/DC converter type) - BD9415FS (New)

BD9415FS is a high efficiency driver for white LEDs and designed for large LCDs. This IC has a built-in boost DC/DC converter that employs an array of LEDs as the light source. BD9415FS has various protection functions against fault conditions, such as over-voltage protection (OVP), over current limit protection of DC/DC (OCP), short circuit protection (SCP), over duty protection (ODP) and open detection of LED string. Therefore, BD9415FS is available for the fail-safe design over a wide range of output voltages.
