The BD94061F-E2, designed by Rohm Semiconductor, Inc., is a high-efficiency driver created for white LEDs, especially suitable for large LCDs. The sophisticated design of the BD94061F-E2 integrates a quasi-resonant (QR) control method DC-DC converter and a continuous current mode (CCM) DC-DC converter. These converters are crafted to supply an appropriate voltage to the light source of the LEDs arranged in a series. Exceptional flexibility is one of its hallmarks, achieved primarily through external current detection resistance, which enables power supply design to adapt according to specific requirements.

Numerous distinguished features add to the BD94061F-E2's capabilities and versatility. These include the option to select between QR or CCM operations through the SEL Pin, an inclusive LED current compensation function for QR, and an under-voltage protection function via the VCC Pin. It also encompasses a leading-edge blanking function through the CS Pin, and the capability for both PWM and ADIM Dimming Operating. Provisions for abnormal detection signal output through the FAILB Pin, and LED PWM dimming over duty protection are included as well.
