Mobile phones Digital cameras and audio devices Portable and battery-powered equipment GENERAL DESCRIPTION The ADP1290 is a high-side load switch designed for operation In addition to operating performance, the ADP1290 occupies between 2.3 V and 13.2 V. This load switch provides power minimal printed circuit board (PCB) space with an area of less 2 domain isolation, helping to extend battery operation. The than 1.5 mm and a height of 0.60 mm. device contains a low on-resistance, N-channel MOSFET that The ADP1290 is available in an ultrasmall, 1 mm 1.5 mm, supports more than 2 A of continuous current and minimizes 6-ball, 0.5 mm pitch WLCSP. power loss. In addition, RDS is constant independent of the VIN ON voltage. The low 15 A quiescent current and ultralow shutdown current of 20 A make the ADP1290 ideal for battery-operated portable equipment. The built-in level shifter for enable logic makes the ADP1290 compatible with many processors and general-purpose input/output (GPIO) controllers.
