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
channel. Inclusion of a low dropout PowerLite
Current
Regulator
(PCR)
increases
device’s
efficiency up to 90%.
The EN/SET logic input functions as a chip enable
and a current setting interface.
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
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.
The device is available in 8-lead TDFN 2 mm x 3 mm
package with a max height of 0.8 mm.
