CL2

Simple 90V, 20mA, Temperature Compensated

Constant Current LED Driver IC

Features

General Description

TheSupertexCL2isahighvoltage,temperaturecompensated,

constant current source. The device is trimmed to provide

a constant current of 20mA±10% at an input voltage of 5.0

- 90V. The device can be used as a two terminal constant

current source or constant current sink.

► 5.0 to 90V operating range (V_A-B)

► 20mA ±10% at 5.0 - 90V

► 0.01%/°C typical temperature coefﬁcient

► Available in TO-243AA (SOT-89), TO-252 (D-PAK),

& TO-92 packages

► Can be paralleled for higher current

Atypical application for the CL2 is to drive LEDs with a constant

current of 20mA. Multiple CL2s can also be used in parallel to

provide higher currents such as 40mA, 60mA or 80mA. The

device is available in TO-243AA (SOT-89), TO-252 (D-PAK),

and TO-92 packages.

Applications

► LED driver

► Industrial lamp indicators

► Signage

► Accent lighting

► Automotive

► Constant current source

► Constant current sink
