Analog Devices, Inc. Low Duty Cycle, 600 mA, 3 MHz Synchronous Step-Down DC-to-DC Converter ADP2102YCPZ-4-R7

Description
Product Details The ADP2102 is a synchronous step-down dc-to-dc converter that converts a 2.7 V to 5.5 V unregulated input voltage to a lower regulated output voltage with up to 95% efficiency and 1% accuracy. The low duty cycle capability of the ADP2102 is ideal for USB applications or 5 V systems that power up submicron subvolt processor cores. Its 3 MHz typical operating frequency and excel-lent transient response allow the use of small, low cost 1 μH inductors and 2.2 μF ceramic capacitors. At medium-to-high load currents, it uses a current mode, pseudofixed frequency pulse-width modulation to extend battery life. To ensure the longest battery life in portable applications, the ADP2102 has a power save mode (PSM) that reduces the switching frequency under light load conditions to significantly reduce quiescent current. The ADP2102 is available in both fixed and adjustable output voltage options with 600 mA maximum output current. The preset output voltage options voltage are 1.875 V, 1.8 V, 1.5 V, 1.375 V, 1.25 V, 1.2 V, 1.0 V, and 0.8 V. The adjustable voltage option is available from 0.8 V to 3.3 V. The ADP2102 requires only three external components and consumes 0.01 μA in shutdown mode. The ADP2102 is available in an 8-lead LFCSP package and is specified for the −40 °C to +85 °C temperature range. Applications USB powered devices WLAN and gateways Point of loads Processor core power from 5 V Digital cameras PDAs and palmtop computers Portable media players, GPS
