Power Management Discretes

Toshiba discrete IC technology offers high-performance load switch ICs and low-dropout regulators for power management applications

Image of Toshiba Semiconductor and Storage's Power Management Discretes Toshiba has released two new load switch families, the ultra-low ON resistance TCK11xG and the low operating voltage TCK20xG. The new load switch ICs offer reverse current blocking and an over-thermal shutdown function. They can provide up to 2 A to 3 A of current, making them quite powerful for their small size.

The TCK111G and TCK112G feature ultra-low switch ON resistance, low quiescent current and a wide input voltage operation from 1.1 V to 5.5 V. Switch ON resistance is only 8.3 mΩ at 5.0 V and -1.5 A for load conditions. It also features an inrush current suppressing slew rate control driver and output auto-discharge function (offered as an option on the TCK112G). This is in a tiny chipscale package (1.0 mm x 1.5 mm, t: 0.5 mm) with 0.5 mm pitch.

The low-voltage load switches TCK206G, TCK207G, and TCK208G have smaller packages than the super-low RON family. They operate at voltages as low as 0.75 V, which makes them a good choice for being directly controlled by a low-voltage controller. They have an RON of approximately 18 mΩ, which is very low considering their even smaller chipscale package (0.9 mm x 0.9 mm, t: 0.5 mm) with 0.5 mm pitch.

For switches where voltage regulation is necessary, Toshiba provides low dropout (LDO) regulators. CMOS-LDO regulators have become the power management ICs of choice for mobile devices, as they enable a low profile, low supply current and low dropout. Toshiba's lineup of LDOs provides 200 mA to 300 mA of output current, with excellent noise-output and ripple rejection characteristics.
