ZD3315EVB Evaluation Board Manual:The ZD3315 contains 4 channels of linear regulated, low
drop out current sources, specifi cally designed to drive up
to 4 strings of LED’s with 150mA sourcing current per channel.
Each LED string operates individually by terminating to
an internal, regulated current sink, which provides matched
and consistent LED current over a wide input supply range.
The LED currents are set by an external resistor, RSET, connected
to the ISET pin. The EN pin provides a chip enable
function and can be used with a PWM pulse to achieve a
dimming control function or a DC voltage can be inserted
into the ISET pin to control the LED currents.
The ZD3315 is available in a 2mm x 3mm 8-pin DFN green package.
