100-240VAC Input: 60W: 2-string: PWM Dimmable LED Driver Reference Design
Texas Instruments
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.
