The LTC3533EDE#PBF from Linear Technology (LT) is a 2A wide input voltage synchronous buck-boost DC/DC converter. This highly efficient converter operates from input voltages that are above, below, or equal to the output voltage, providing a continuous transfer function across all operating modes. It is ideal for applications using single-cell lithium-ion/polymer or multi-cell alkaline/NiMH batteries where the output voltage may vary within the input voltage range.
Key electrical specifications include an input voltage range of 1.8V to 5.5V and an output voltage up to 5.25V. It can deliver 0.8A continuous output current when VIN > 1.8V and up to 2A continuous output current when VIN > 3V. The device boasts up to 96% efficiency due to synchronous rectification and features programmable Burst Mode operation, reducing quiescent current to 40µA. The switching frequency is programmable from 300kHz to 2MHz.
Other features include <1µA shutdown current, short circuit protection, programmable soft-start, current limit, and thermal shutdown. The LTC3533EDE#PBF is housed in a small, thermally enhanced 14-lead DFN package measuring 3mm x 4mm x 0.75mm. Its operating temperature range is -40°C to 85°C.
This converter is well-suited for applications such as GSM modems, handheld instruments, digital cameras, smartphones, media players, and miniature hard disk drive power supplies.
