ROHM BD93941FP-E2 LED Driver IC

BD93941FP is a high efficiency driver for white LEDs and designed for large LCDs. These ICs are built-in a boost DCDC converters that employ an array of LEDs as the light source. BD93941FP has some protect function against fault conditions, such as the over-voltage protection (OVP), the over current limit protection of DCDC (OCP), the short circuit protection (SCP), the open detection of LED string. Therefore BD93941FP is available for the fail-safe design over a wide range output voltage.
