PT6985

High Precision Buck LED Driver

DESCRIPTION

FEATURES

The PT6985 is a non-isolated buck and applicable to 85V

AC ~ 265V AC input voltage rangefor LED lighting.



Integrates 500V Power MOSFET

CRM Mode

No Auxiliary Winding for Sensing and Supplying

Low Operating Current

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。

Universal Input Voltage Range

±5% Output Current Accuracy

LED Open/Short Circuit Protection

VIN Under Voltage Protection

CS Resistor Short Circuit Protection

Temperature Intelligent Control

System Auto-Restart Function

SOP-8 Package

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. It has a few

external components, saves the cost and volume system.

APPLICATIONS



LED Bulb lamp, LED PAR lamp

LED Tube lamp

Other LED lighting

The multi-protection features of PT6985 greatly enhance

the system reliability and safety. The PT6985 provides CS

resistance short-circuit protection, short LED protection,

open LED protection, VIN under voltage protection,

temperature intelligent control, etc.
