LTC3533EDE#PBF Description

Short technical summary and product information.

The LTC3533EDE#PBF is a wide input voltage range, highly efficient, fixed frequency, buck-boost DC/DC converter. It operates from input voltages that are above, below, or equal to the output voltage, making it suitable for single-cell lithium-ion/polymer or multi-cell alkaline/NiMH applications. The device supports input voltages from 1.8V to 5.5V and can provide up to 2A of continuous output current when VIN > 3V.

Key features include synchronous rectification for up to 96% efficiency, programmable Burst Mode operation with low quiescent current, and a programmable switching frequency from 300kHz to 2MHz. It also offers features like output disconnect in shutdown and a shutdown current of less than 1µA.

The LTC3533EDE#PBF is housed in a small, thermally enhanced 14-lead DFN package measuring 3mm x 4mm x 0.75mm, suitable for surface mount applications. Its versatility makes it ideal for portable devices and other power-sensitive applications.

Applications include GSM modems, handheld instruments, digital cameras, smart phones, media players, and miniature hard disk drive power supplies.
