PT6983A
High Precision Buck LED Driver
DESCRIPTION
FEATURES
The PT6983A 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 PT6983A integrates high precision current detection
and constant current circuit, realizes high precision LED
constant current and excellent line voltage regulation. The
PT6983A 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 PT6983A integrates a 500V power MOSFET, uses
the source driver architecture, with a low operating
current, so the PT6983A 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 PT6983A greatly enhance
the system reliability and safety. The PT6983A provides
CS resistance short-circuit protection, short LED
protection, open LED protection, VIN under voltage
protection, temperature intelligent control, etc.
