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
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
TYPICAL APPLICATION CIRCUIT
supports a range of input voltages from 2.7 V to
5.5 V.
The device is available in 8-lead TDFN 2 mm x 3 mm
package with a max height of 0.8 mm.
