FEATURES
DESCRIPTION
LP5560 is a programmable LED driver that can
2
Programmable Blinking Sequence with Current
generate variety of blinking sequences with up to
Rise and Fall Time Control
three pulses of different length per sequence. Blinking
Default Blinking Sequence for Simple Systems
sequences can be programmed through single wire

interface. Programmable parameters include on and
off times as well as rise and fall times. Default
Single-Wire Interface
sequence is programmed into LP5560 to enable the
Constant Current High Side Output Driver
use of device in simple systems without programming

capabilities.
No External Components
Very low headroom voltage eliminates the need for
0.891 mm (Max.) x 0.891 mm (Max.) x 0.6
boost converter. Indicator LEDs can be driven directly

size.
Adjustable Output Current from 2.8 mA to 19.5
mA LP5560 is available in TI’s tiny 4-bump DSBGA
package with 0.4 mm pitch.
Wide Input-Voltage Range: 2.7V to 5.5V
