General Description

The PT6985 is a non-isolated buck and applicable to 85V AC ~ 265V AC input voltage rangefor LED lighting.

The PT6985 integrates high precision current detection and constant current circuit, realizes high precision LED constant current and excellent line voltage regulation.

The PT6985 works in CRM mode, the LED current is constant with inductance and LED output voltage change, good load regulation。 The PT6985 integrates a 500V power MOSFET, uses the source driver architecture, with a low operating current, so the PT6985 doesn’t need the auxiliary winding for sensing the output current and supplying the chip.

Overview

DESCRIPTION The PT6985 is a non-isolated buck and applicable to 85V AC ~ 265V AC input voltage rangefor LED lighting.
