General Description

BD93941EFV and 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.

BD93941EFV and BD93941FP have 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.
