Manufacturer:IR Description: The ILED is the constant current programmed by the RLED. When the feedback voltage on the FB terminal reaches above the reference voltage VREF (i.e., ILED is above the level programmed by RLED), the output capacitor C2 delivers the ILED. Once the feedback voltage drops below the reference voltage (i.e., ILED drops below the level programmed by the RLED), the MOS switch is turned on, then the current of the inductor L1 begins increasing. When the switch current reaches 250mA, the MOS switch is turned off, then the L1 delivers current to the output through the diode D1 as the inductor current drops. After that, the MOS switch is turned on again and the switch current increases up to 250mA. This switching cycle continues until the ILED reaches the level programmed by the RLED, then the ILED current is maintained constant. |
