Smartphone, Tablets, Smart-watches are driving the portable electronic toward a new era where the finest pitch and highest performance technologies are immediately exploited. The end-users, you and me, are directly involved in this competition because we continuously want the Highest resolution display, the Fastest processor and the Highest communication bandwidth. A handset powered with a single cell 3.6V Lithium Ion battery requires various Power Management functions to handle the battery charging (direct charging or wireless) as well as the power distribution/conversion up-and-down for supplying: the processor (around 1V), the Radio Transmitter (around 3.3V), the Display (up to 18V), the camera, the GPS, the motion sensor, the USB terminal, the etc. Electronic engineers today, are required to deeply understand the needs for every application in order to participate to the design of the application itself or to design the best power management solution for it. The challenge consists of providing the highest power efficiency solution that fits into a very limited PCB area and has a very low cost! This conference is outlined as follows A quick overview of electronic component technologies employed in the smartphone A presentation of the power management needs for the principal peripherals (processor, display, RF interface) Review of the Power Management techniques and Integrated Circuit (PMIC) resources Challenges and perspectives
