Power Control

The IES5528 phase control and triac triggering integrated circuit is designed for various mains power control applications including phase control, soft start for motor / power speed control and time proportional temperature control.

The IES5528 superceeds the OM5428 and like the OM5428 offers similar features as the now obsolete TCA280B.

The IES5528 is designed for uses with modern high reliability, high sensitivity three-quadrants or snubberless triacs such as in the NXP Semiconductor range.
