Three new designs using LYTSwitch-7, Power Integrations' latest LED driver IC, are

now available for download. LYTSwitch-7LED driver ICs have a component count that

is approximately 40% less than for conventional circuits and are capable of delivering

up to 22 watts without a heatsink in a very small SO-8 footprint.

Each of the following designs are dimmable, power factor corrected, and non-isolated:
