SP1821
Four Channels Constant Current LED Driver
DESCRIPTION
The SP1821 is a linear constant current driver designed
to drive multiple LEDs in series from a high input
voltage rail. The driver acts as a high current matched,
four-channel current source ensuring constant LED
current for a range of input voltages. The device can
drive up to 25mA load current per string with an
external resistor. The SP1821 can provide lowest cost
for various applications. Internal thermal protection
automatically turns off LED current to prevent
overheating. The dimming can be achieved by
controlling the ISET input or by feeding a PWM signal to
the EN pin. The device can be shut down by setting
Enable low.
