DESCRIPTION The PT6984A is a non-isolated buck and applicable to 85V AC ~ 265V AC input voltage rangefor LED lighting. The PT6984A integrates high precision current detection and constant current circuit, realizes high precision LED constant current and excellent line voltage regulation. The PT6984A works in CRM mode, the LED current is constant with inductance and LED output voltage change, good load regulation。 The PT6984A integrates a 500V power MOSFET, uses the source driver architecture, with a low operating current, so the PT6984A doesn’t need the auxiliary winding for sensing the output current and supplying the chip. It has a few external components, saves the cost and volume system. The multi-protection features of PT6984A greatly enhance the system reliability and safety.
