全電壓大瓦特數LED平板燈方案

KT2616 LED Lighting solution

AC/DC 20W-80W High PF and High Efficiency LED Controller

Non-isolation Boost LED Lighting Driver with Active PFC 

 

General Description

The KT2616 is a PFC boost controller IC with one channel LED regulator. PFC controller offers high input power factor and low harmonic. It features a voltage amplifier for feedback error processing, a simple multiplier for generating a current command proportional to the input voltage, a current-sense (PWM) comparator, PWM logic and ad totem pole driver output for an external MOSFET.

 

Features

  • Boost Controller to achieve high PF and low THD
  • Wide AC input range – from 85Vac to 265Vac
  • IC for sinusoidal line-current consumption
  • No visible flicker
  • Totem pole output with active shutdown
  • Zero current detector for discontinuous operation mode
  • Output over voltage protection
  • Programmable LED current
  • MSOP-10 package

 

Typical Application

  • 60W LED Lighting
  • VAC=200V~240V, LED voltage=380V, LED current=160mA
  • High Efficiency >94%
  • High PF> 0.99
  • Low THDi < 5%
