Charge Pump With 1000mA Flash Mode, 275mA Spotlight Mode, And I 2 C Interface

The SC628A is a high ei ciency Charge Pump LED Driver using Semtech’s proprietary Charge Pump technology. Performance is optimized for use in single-cell Li-ion battery applications. The load and supply conditions determine whether the Charge Pump operates in 1x, 1.5x, or 2x mode. The Charge Pump provides continuous spotlight mode current or pulsed l ash mode current to an LED using a dedicated current sink. In l ash mode, a l ash-timeout feature turns of the l ash if active for longer than 1 second. In spotlight mode, the timeout feature is disabled to allow continuous operation of the LED The SC628A uses an I 2 C compatible serial Interface to set the l ash mode or the spotlight mode current. The l ash/ spotlight output is triggered via either the I 2 C Interface or a dedicated l ash enable pin (FLEN). In sleep mode, the device reduces quiescent current to 100μA while continuing to monitor the serial Interface Total current reduces to 0.1μA in shutdown. By Semtech Corporation
