Load switch ICs operate at 1.1V with on-res of 55 milli ohms in WCSP6 package

Toshiba America Electronic Components has unveiled new load switch ICs for mobile devices. The TCK101G and TCK102G are low consumption current load switch ICs with slew rate control driver for power management. Featuring low voltage operation at 1.1V and a low ON-resistance characteristics of 55milli ohms (typ.) (VIN = 3.3V, IOUT = 500mA) in a 0.4mm pitch ultra small WCSP6 (0.8mm x 1.2mm, t: 0.64mm (max.)) package, these ICs come standard with an inrush current limiter and over temperature protection circuit. An output auto-discharge function is also available. Toshiba's new lineup of 200mA output LDO regulators control inrush current, making them suitable for a wide range of applications including mobile phones, portable audio players, notebook PCs, DSC/DVC, and other small mobile devices. Toshiba's TCK104G and TCK105G are load switch ICs for power management and current limit function featuring wide input voltage operation from 1.1 to 5.5V. They feature low switch ON- resistance at 65 milli ohms typical at 3.3V, 700mA load condition and a slew rate control driver, with thermal shutdown and an output auto-discharge function. Output current type is available, simplifying device selection and design. Available in a 0.4mm pitch ultra small package WCSP6 (0.8mm x 1.2mm x 0.64mm (max)), these devices are ideal for portable applications that require high-density board assembly ...
