Semtech Adds Ultra-Low RDS(on) Load Switch Family to FemtoSwitch Platform

CAMARILLO, Calif., Feb. 14, 2017 ? Semtech Corporation (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced the latest family of load switches in its FemtoSwitch™ product platform. The new, ultra-low RDS(on) load switches are ideal for 5V, 15W USB Power Delivery (USB-PD) type-C port controller applications and other power rail switching applications, such as battery-powered portable electronics.

This product family extends Semtech’s FemtoSwitch platform of high-performance analog load switch ICs. It features slow, soft start when the switch is turned-on to limit the in-rush current. Its output pin provides an auto-discharge function for H-version products, and it is protected from overload faults with a 3A current-limit, as well as from over-temperature with a shutdown circuit.

“This expansion to our FemtoSwitch load switch platform enhances Semtech’s high performance, low power product portfolio,” said Francois Ricodeau, Product Line Manager for Semtech’s Power and High-Reliability Products Group. “By providing ultra-low RDS(on) load switches geared toward USB-PD type-C port controller applications, we are able to meet the demands of the fast-growing portable electronics market.”

Key Features of the Ultra-Low RDS(on) Load Switch Family

  • Sophisticated integrated circuitry for ultra-low, 9m? RDS(on) to minimize voltage drop and energy dissipation across the switch
  • Controlled soft start to limit in-rush current
  • 3A continuous output current to protect from overload faults
  • Over temperature protection
  • Ultra-small 0.9mm x 1.4mm package

Pricing and Availability

The ultra-low RDS(on) load switches (SKU: SC33001A and SC33001AH) are available immediately in production quantities and are priced at $0.20 each in 1,000-piece lots. Semtech offers comprehensive design assistance, including field- and factory-based support. Datasheets, volume pricing, and delivery quotes, as well as evaluation kits and samples, are available at www.semtech.com/info.
