ADP2102YCPZ-3-R7

ADP2102 is a synchronous step-down DC-DC converter that converts 2.7 V to 5.5 V unregulated input voltages to lower regulated output voltages with up to 95% efficiency and 1% accuracy. ADP2102's low duty cycle capability is ideal for USB applications or 5 V systems powering subvolt processor cores. The typical operating frequency of 3 MHz and excellent transient response allow the device to use a small, low-cost 1 μH inductor and a 2.2 μF ceramic capacitor. For medium to high load currents, the device uses current-mode, pseudo-fixed-frequency pulse-width modulation to extend battery life. To ensure maximum battery life for portable applications, ADP2102 has a built-in Power Saving Mode (PSM) that reduces the switching frequency at light loads, significantly reducing quiescent current.

ADP2102 offers both fixed and adjustable output voltage options, with a maximum output current of up to 600 mA. Preset output voltage options include 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. Adjustable voltage options range from 0.8 V to 3.3 V. ADP2102 requires only three external components and consumes only 0.01 μA in shutdown mode.

ADP2102 is available in an 8-pin LFCSP package and is rated for a temperature range of −40 °C to +85 °C.
