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 TOFF of
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.
