The LTC3547EDDB-1#PBF is a dual, constant-frequency, synchronous step-down DC/DC converter manufactured by Analog Devices. It features high efficiency, achieving up to 96%, and can deliver 300mA of continuous output current per channel. The device operates with an input voltage range of 2.5V to 5.5V, making it suitable for Li-Ion and USB powered applications.
Key electrical characteristics include a low quiescent current of 40µA during operation and an ultralow shutdown current of less than 1µA. It operates at a constant switching frequency of 2.25MHz and includes a 0.6V reference voltage, allowing for low output voltages. The converter is internally compensated for ceramic capacitors and features independent internal soft-start for each channel.
Packaged in a low-profile 3mm x 2mm DFN package with a height of 0.75mm, the LTC3547EDDB-1#PBF is designed for space-constrained applications. Its synchronous rectification and constant-frequency operation contribute to excellent line and load transient response. Automatic low ripple Burst Mode operation enhances efficiency at light loads, extending battery life in portable systems.
