PRODUCT DESCRIPTION

The IK2312 is a pulse width modulated (PWM) LED driver control IC. It allows efficient

operation of low current LED strings from voltage sources ranging up to 400VDC. The IK2312

include an internal high-voltage switching MOSFET controlled with fixed off-time T_OFFof

approximately 10,5μs. The LED string is driven at constant current, providing constant light output

and enhanced reliability. The IK2312 does not produce a peak-to-average error, and therefore

greatly improves accuracy of the LED current. The IK2312 designed for using low inductance value.

The average current control scheme of the IK2312 provide good LED current regulation throughout

the universal AC input voltage range of 85 to 264V AC or DC input voltage of 20 to 400V.
