Description

PMP6024 is an offline, LED driver circuit consisting of an isolated, power-factor corrected, constant output voltage flyback converter followed by two DC/DC buck LED current controllers.  It is suitable for indoor or outdoor area lighting applications of 3500-5000 lumens (depending upon LED selection).  LED brightness is controlled by a 3.3V, 10kHz PWM signal which is converted to a DC level adjustment of the LED string currents avoiding PWM modulation of the light output.

Features
  • Power Factor Corrected > 0.9
  • Analog LED current adjustment from 1kHz-10kHz PWM input
  • 350:1 dimming ratio
  • 100-240VAC Input, up to 60W output
