LDS8680  
800 mA White LED Driver for Photo Flash  
FEATURES  
o
o
o
1-x and 2-x Charge pump modes  
Low dropout PowerLite™ Current Regulator*  
Drives up to 2 LEDs at 400 mA  
simultaneously or one LED at 800 mA  
o
Smart OneWire™ LED current programming  
and PWM mode LED current control  
channel. Inclusion of a low dropout PowerLite™  
Current Regulator (PCR) increases device’s  
efficiency up to 90%.

Power efficiency up to 90%  
Low current shutdown mode < 1 µA  
Short circuit current limiting  
The EN/SET logic input functions as a chip enable  
and a current setting interface.  
Thermal shutdown protection  
The LEDs current is programmable by Smart  
OneWire™ digital interface in 32 steps from 52 to  
800 mA for LEDA channel or in 16 steps from 52 to  
400 mA for LEDB channel. Every LED may be turned  
on/off or programmed separately  
Timeout to protect LED at high currents  
8-pin 2 x 3 x 0.8 mm TDFN package  
APPLICATION  
o
o
Photo flash plus red eyes reduction  
Low noise input ripple is achieved by operating at a  
constant switching frequency, which allows the use of  
small external ceramic capacitors. The charge pump  
supports a range of input voltages from 2.7 V to  
5.5 V.  
White LED photoflash for cell phones and  
still cameras  
DESCRIPTION  
The LDS8680 is a high efficiency charge pump with  
low dropout voltage that can drive two LEDs at 400  
mA each simultaneously or one LED at 800 mA per  
The device is available in 8-lead TDFN 2 mm x 3 mm  
package with a max height of 0.8 mm.
