Rohm Semiconductor BH6941KN-E2 is a 4-output DC-DC regulator featuring a switched capacitor (charge pump) topology. This LED driver IC is designed for efficient operation, with an internal switch capable of delivering up to 20mA per channel. The BH6941KN-E2 operates from a supply voltage range of 2.8V to 4.5V, providing a fixed output voltage of 4.5V. Its high switching frequency of 1.2MHz contributes to compact external component selection and efficient power conversion. The device is housed in a 20-VQFN package for surface mounting and is supplied on tape and reel. This component is suitable for applications requiring precise LED current regulation and is commonly found in portable electronics and display backlighting systems. The operating temperature range is -30°C to 80°C.
