LED Driver ICs in 2mm High Package

Power Integrations announced the availability of LinkSwitch-PH LED driver ICs in a low-profile eSIP-7F (L package) that measures just 2 mm high. The new package targets LED-based replacements for fluorescent tubes, where very low-profile packages are required to fit into the small space available behind the LED circuit board, as well as other applications where board height is constrained.

LinkSwitch-PH devices in the 2-mm L package have the same thermal and electrical performance as previously released ICs in the 10 mm high eSIP-7C (E package). The new L package features a heat transfer tab on top of the device which is electrically quiet (source potential) so any additional heatsink does not contribute to electrical noise propagation.

Power Integrations' LinkSwitch-PH single-stage, primary-side controlled, LED driver ICs feature >90% efficiency and >0.9 power factor. The innovative topology eliminates the need for unreliable electrolytic bulk capacitors and opto-isolators, making the devices ideal for high-reliability industrial, commercial, and exterior solid-state lighting (SSL) applications. Suitable for designs from 4 W to 55 W, SSL driver ballasts based on LinkSwitch-PH ICs easily satisfy ENERGY STARĀ® and EN61000-3-2 class C and D requirements.

LinkSwitch-PH samples in the L package are available now, priced from $1.01 for 10,000-piece quantities.
