CAT4003B, CAT4004B
Constant Current
Programmable LED Driver
with 32 Dimming Levels
Description
The CAT4003B and CAT4004B provide respectively three and four
matched low dropout current sources to drive LEDs. The CAT400XB
requires no external RSET resistor. The LED current is internally set
to 25 mA when the device is first enabled. Each LED channel includes
an individual control loop allowing the device to handle a wide range
of LED forward voltages while still maintaining tight current

matching.
The EN/DIM logic input supports the device enable and a digital
dimming interface for setting the LED channel current with 32 linear
dimming levels.
LEDs can be powered directly from a Lithium ? ion battery due to the
low dropout (75 mV at 20 mA) current sinks.
Package options are available in the 4 ? channel tiny 8 ? pad UDFN
2 mm x 2 mm with a max height of 0.55 mm, and 3 ? channel in the
6 ? lead TSOT ? 23, TSOP and SC ? 70.
