IZ9921, IZ9922, IZ9923 HIGH-VOLTAGE LED DRIVER WITH BUILT-IN MOSFET SWITCH IZ9921, IZ9922, IZ9923 are high-voltage LED driver control ICs with built-in MOSFET switch and intended for LED lighting control. They allow efficient operation of LED strings from voltage sources ranging up to 400VDC. The IZ9921/22 includes an internal high-voltage switching MOSFET controlled with fixed off-time TOFF of approximately 10µs. The LED string is driven at constant current, thus providing constant light output.
