    Part Number: PMP6024 Other Parts Discussed in Thread: LM2596 , , LM3409 I want to use this design for one of our upcoming project. I want to control dimming using WiFi or BLE or any other external RF-SOC. I have following requirements. 1. I need 3.3V or…

  • RE: PMP6024: Start up circuitry overheated

    Hello Conny, Did you use the same transformer as the PMP6024 uses? Can you look to see if the Q1 circuit is getting disabled after power on? If it is supplying IC power through Q1 instead of the primary bias winding it is not working correct. Also, Q1…

  • Reference design PMP6024

    Other Parts Discussed in Thread: PMP6024 Hello, We would like to use the reference design PMP6024 (100-240VAC Input, 60W, 2-string, PWM Dimmable LED Driver) almost as it is. We are planning additional wireless connectivity but the 100-240VAC power supply…

    Part Number: TPS92314A Other Parts Discussed in Thread: PMP6024 , UCC28810 , LM3447 , TPS92210 I need to design a small size, isolated 50W LED driver. The purpose of this project is to replace an existent driver. I have many led panels in warehouse with…

  • RE: LM3445: AN2069 Dimmer Circuit not Working

    Hello, I was looking at your schematic an noticed this. A flyback should have all secondary windings in the same polarity and the primary swapped (looking at the dots). Using your schematic, when the MOSFET is on pin one is Vin and pin 3 is GND, the primary…
