SC628A  
LED Flash Driver  
Charge Pump with 1000mA Flash Mode,  
275mA Spotlight Mode, and I2C Interface  
POWER MANAGEMENT  
Features  
Description  
„
„
„
Input supply voltage range — 3.0V to 5.5V  
Charge pump modes — 1x, 1.5x and 2x  
Flash LED — 1000mA max in flash mode, 275mA max  
continuous for spotlight  
The SC628A is a high efficiency 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.  
„

„
„
„
„
„
„
Charge pump frequency — 250kHz  
I2C compatible interface up to 400kHz  
External flash control pin to sync with camera  
One second flash time out with disable feature  
Automatic sleep mode (flash o) IQ = 100μA  
Low shutdown current — 0.1μA (typical)  
Ultra-thin package — 3mm x 3mm x 0.6mm  
Fully WEEE and RoHS compliant  
The charge pump provides continuous spotlight mode  
current or pulsed flash mode current to an LED using a  
dedicated current sink. In flash mode, a flash-timeout  
feature turns off the flash if active for longer than 1 second.  
In spotlight mode, the timeout feature is disabled to allow  
continuous operation of the LED.  
Applications  
The SC628A uses an I2C compatible serial interface to set  
the flash mode or the spotlight mode current. The flash/  
spotlight output is triggered via either the I2C interface or  
a dedicated flash enable pin (FLEN).  
„
„
Cellular phone flash  
PDA flash  
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.
