DESCRIPTION

The PT6988 is a high precision buck LED Driver ICintended for dimming products with ordinary switch byon/off state in dimming time. The IC has a wide rangeinput range which is 85V~265V and the default dimmingstate is three Level.

The PT6988 integrates high precision current detectionand constant current circuit which can realize highprecision LED constant current and excellent line voltageregulation. The PT6988 works in CRM mode, the LEDcurrent is constant with inductance and LED outputvoltage change, good load regulation.

The PT6988 integrates a 500V power MOSFET, uses thesource driver architecture, with a low operating current, sothe PT6988 doesn’t need the auxiliary winding for sensingthe output current and supplying the chip. It has a fewexternal components, saves the cost of volume system.

The multi-protection features of PT6988 greatly enhancethe system reliability and safety. The PT6988 provides CSresistance short-circuit protection, short LED protection,open LED protection, VIN under voltage protection,temperature intelligent control, etc.
