BD94062F - ROHM

BD94062F high efficiency driver

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.
