Description

The STEVAL-TLL012V1 demonstration board

demonstrates the performance of the STP4CMP,

a charge pump based 4-channel LED driver

designed for RGB illumination or LCD display

backlighting.

This device works off a battery with an input

voltage between 2.7 V - 5.5 V. The device

generates regulated current sinks with high

absolute and channel-to-channel accuracy to

drive up to 4 LEDs.

It can support LEDs with forward voltage as high

as 3.8 V.

The current sink for each channel can be set with

4 individual external resistors. Each channel is

controlled independently.

The PWM control can be applied directly to the 4

EN (enable) inputs to provide brightness control.

Operating voltage range: 2.7 V to 5.5 V

Full RGB function support

4-channel LED driver with individual ON/OFF

control directly from input pins

Individual programmable output current for the

4 channels through 4 external resistors with a

max. capability of 30 mA

Absolute output current accuracy of max. ±7%

and channel-to-channel mismatch of max. ±

Selectable charge pump enable/disable

Thermal protection

RoHS compliant

4-channel LED driver with charge pump based on the STP4CMP
