Hi,
I have designed, developed prototypes, tested circuits for LED lighting (Tubes and Bulbs - 5W to 30W) using LinkSwitch IC family and OSRAM LEDs.
Have simulated various circuits using LTSpice-IV.
The amount and timeline are indicative, and will update actual quote depending on scope of work (Design only on LTSpice or Prototyping or Production).
Regards,
R.Senthil.
