2A load switches target consumer devices

Semtech Corp. has released the SC724/5/8/9 load switch platform in a 0.76mm x 0.76mm, 4 bump, 0.5mm pitch chip scale package (CSP). The SC724/5/8/9 switches offer 2A, 1.1V to 3.6V power rail with controlled turn-on and turn-off profiles, noted the company.

The SC724 and SC728 provide fast turn-on (19.5us at 1.8V_IN) and float the output when disabled, while the SC725 and SC729 provide slower turn-on (490us at 1.8V_IN) and discharge the output when disabled. The load switches are ESD hardened to greater than 3kV for robust circuit protection.

The SC724/5/8/9 feature V_IN range of 1.1V to 3.6V, I_OUT of up to 2A and very low R_ON down to 36m?. The devices also boast controlled turn-on and turn-off (optional fast/slow turn-on, and auto-discharge).

Applications of the devices include portable applications such as wearable electronics, portable video cameras, smartphones and tablets; and non-portable applications such as HDTVs, set-top boxes and networking devices.

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.
