PT6982B

High Precision Buck LED Driver

DESCRIPTION

FEATURES

The PT6982B is a non-isolated buck and applicable to 85V

AC ~ 265V AC input voltage rangefor LED lighting.



Integrates 500V/1A Power MOSFET

CRM Mode

No Auxiliary Winding for Sensing and Supplying

Low Operating Current

The PT6982B integrates high precision current detection

and constant current circuit, realizes high precision LED

constant current and excellent line voltage regulation. The

PT6982B 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 PT6982B integrates a 500V power MOSFET, uses

the source driver architecture, with a low operating

current, so the PT6982B 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 PT6982B greatly enhance

the system reliability and safety. The PT6982B provides

CS resistance short-circuit protection, short LED

protection, open LED protection, VIN under voltage

protection, temperature intelligent control, etc.
