Other Parts Discussed in Thread: TPS92314
I want to design 3,6,9W LED driver using TPS92314. I got this data sheet from TI website.But to calculate the value of inductor I need to know what is VLED and ΔIpeak. Please help me to find out the values of…
Other Parts Discussed in Thread: TPS92314 I would like to make LED driver using TPS92314 for 3W, 6W and 9W LED bulbs. I got a circuit from TI for the above application.
I am attaching the circuit for the above application.The TI team told me to change the…
Dear Chuck,
Sorry for the late Update. we have found ideas to reduce heat on MOSFET and transformer. by tuning the delay resistor, re-calculating the turns of transformer.
Product is successfully working for 20-30W driver range.
I need a clarification…
Other Parts Discussed in Thread: TPS92314 Hello,
I found a circuit from the document "SLVA663" Low cost, Single Inductor Non-Isolated AC/DC LED Driver Design using TPS92314. This is the only one circuit that no need the transformer that I found.…
Actually both of them are correct.
The first link you show is the user guide for the EVMs which is for non-dimmable application.
TPS92314 is also compatible to dimmable applications. We have a reference design called Triac dimmable Flyback LED Driver…
Other Parts Discussed in Thread: TPS92314 Dear Sir
Good days,
May we check if Tps92314 reference design PMP4347 can driver 42V/0.66A output?
or if any suggest transform spec can advice us?
Best regards,
Bogey
Please provide circuit modification required with transformer design for
1. PMP8010 for 17.5V/400mA
2. PMP8011 for 17.5V/660mA
regards..

Hello,
The LM5023 is a QR flyback controller that does not have power factor correction. At best I believe you can achieve a PF of 0.45 with this device. To achieve more than that you will reguire power factor correction.
The TPS92314 is a primary side…
