Abstract: lithium-ion (Li+) battery. The operating voltage from most Li+ cells is 3V to 4.2V, while a WLED's forward , + battery's operating range is not enough to bias WLEDs. Two approaches are commonly used to generate , IQ is usually small compared to the WLED's load current, the efficiency can be closely approximated , voltage is more than the WLEDs' forward voltage (VF). The key to utilizing 1x mode for the lowest , positive-charge-pump WLED solution uses a pFET bypass switch to connect the battery voltage to the WLEDs, as shown in ... Maxim Integrated Products

Abstract: and ILED is the current through the WLEDs. A typical application with 10 WLED (VOUT = 30V) with a , more power than a meager 0.6W 10 WLED application, it should be able to drive more WLEDs. If one , for all the WLEDs will be 20mA. Since there are differences between the WLED's forward voltage, the , WLED makes the LCD displays bright and pleasant to the human eye. In order to make the WLEDs emit light, a forward voltage must be applied across the anode and the cathode of the WLEDs. The MIC2297 MIC2297 is ... Micrel Semiconductor
