General Description

BD94062F is a high efficiency driver for white LEDs and

designed for large LCDs. BD94062F has a built-in

quasi-resonant(QR) control method DCDC converter and

continuous current mode(CCM) DCDC converter that

can supply appropriate voltage to the light source of

LEDs series array. By external current detection

resistance, it achieves a power supply design with high

flexibility.
