Semtech Corporation today announced the SC724/5/8/9 2A load switch platform in a tiny 0.76mm x 0.76mm, 4 bump chip scale package (CSP) with industry leading on-resistance (Ron) of just 36 mohms. The SC724/5/8/9 switches offer a 2A, 1.1V to 3.6V power rail with controlled turn-on and turn-off profiles. The SC724 and SC728 provide fast turn-on (19.5µs at 1.8Vin) and float the output when disabled, while the SC725 and SC729 provide slower turn-on (490µs at 1.8Vin) and discharge the output when disabled. The load switches are ESD hardened to greater than 3kV for robust circuit protection.
"The SC72X load switch family enables tiny circuit footprints and increases performance for high 2A current, low 36 mohm Ron, and extensive protection," said Andy Khayat, Senior Director for Consumer Power in Semtech's Power Management Products Group. "Semtech's customers can now achieve super small designs with extended battery life and high reliability."
Applications are expected to include wearable electronics, portable video cameras, smart phones, tablet computers, HDTVs, set-top boxes, networking devices, and so on. The SC724/5/8/9 parts are available immediately in production quantities and are priced at $0.32 each in 5,000-piece reels. The ordering codes are SC724CSTRT, SC725CSTRT, SC728CSTRT and SC729CSTRT. Evaluation boards are also available.
