Analog Devices Inc. LTC3553EUD is a highly integrated USB power manager designed for handheld and mobile device applications. This power management IC (PMIC) simplifies the power architecture by incorporating a high-efficiency synchronous step-down DC/DC converter, a linear charger for single-cell Li-ion batteries, and a power path controller. The device efficiently manages power from USB sources, optimizing battery charging and system power delivery. Key features include a low quiescent current of 12µA, enabling extended battery life in standby modes. The LTC3553EUD operates within a supply voltage range of 4.3V to 5.5V. It is available in a compact 20-QFN (3x3) package, suitable for space-constrained designs. The surface mountable component is specified for operation across an industrial temperature range of -40°C to 85°C.
