SP1821

Four Channels Constant Current LED Driver

DESCRIPTION

APPLICATIONS

MR16 and other decoration light source

General reading lighting

Display Backlight

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 I_SETinput or by feeding a PWM signal to

the EN pin. The device can be shut down by setting

Enable low.
