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

Universal Current Limiter based on a LED driver
This design is a current limiter based on a LED driver. It can be used for various applications and changed easily to a different current limit. PMP8531 uses LM3409 buck controller. An excel spreadsheet shows two different configurations (current source or eletrical fuse) and helps the designer to quickly achieve a working design.

Non sync buck controller with 24V input and 18V @ 4.2A output
PMP7755 is a non-synchronous buck controller for LM3409 with 24V DC input and 18V output@ 4.2A. The load is 9 strings with 6 LEDs per string. It uses a motion detector with PIR (passive infarared) dimming as well as 0-10V analog dimming. It has differential high side current sensing which enables setting the dimpoint on PIR. It also has a turn on/off delay.
