Toshiba Launches New Lineup of Load Switch ICs that Reduce System Power Consumption

Feature Low On-Resistance, Low Quiescent Current

IRVINE, Calif., Feb. 23, 2016 — (PRNewswire) —   Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced the introduction of three new single-chip load switch ICs: the TCK106AF, TCK107AF and TCK108AF. By mounting high performance chips on the industry standard SOT-25 package, Toshiba's new ICs feature: low on-resistance, low quiescent current, low loss, low standby current, high performance switching characteristics, and mountability for general use. The new products help reduce the power consumption of various types of electronic equipment, including mobile devices*1.

Fabricated using a Toshiba CMOS process that contains an output transistor and an output driver, the new single chip IC load switches provide a smaller footprint than switches composed of multiple discrete components, making them well-suited to space-critical portable applications. The TCK106AF, TCK107AF and TCK108AF help reduce power consumption in applications including tablets, laptops, DSCs, DVCs, and audio and gaming equipment.

In addition, with integrated slew rate control drivers and low on-resistance P-ch MOSFETs and N-ch MOSFETs, Toshiba's load switch ICs reduce system power consumption via power supply distribution or power supply control for each function block. The new products allow for low-leakage load switching, while maintaining a low on-resistance.

"We've developed these new power supply ICs to meet the requirements of electronic equipment that needs to be driven by batteries for extended periods of time," noted Talayeh Saderi, business development manager for TAEC. "The new products enable safe and stable system design within a compact space, and are suitable for power supply systems that require precise sequence control."

Key Features:
