The LTC3546EUFD#TRPBF from Analog Devices is a dual, constant-frequency, synchronous step-down DC/DC converter designed for medium power applications. It offers configurable output current capabilities, supporting 3A/1A or 2A/2A configurations.
This regulator operates from a 2.3V to 5.5V input supply and provides adjustable output voltages ranging from 0.6V to 5V. The switching frequency can be set to 2.25MHz or adjusted between 0.75MHz and 4MHz, or synchronized to an external clock. Internal synchronous power switches ensure high efficiency, up to 96%, without the need for external Schottky diodes. User-selectable modes like Burst Mode operation, pulse skipping, and forced continuous operation allow for a trade-off between ripple noise and power efficiency.
The device supports low dropout configurations and can operate at 100% duty cycle. In shutdown mode, it consumes less than 1µA. It is available in a 28-lead QFN (4x5) package, suitable for surface mounting.
Key features include dual outputs, adjustable voltage, high efficiency, and low shutdown current, making it suitable for applications such as netbooks, ultra-mobile PCs, PC cards, wireless and DSL modems, and point-of-load DC/DC conversion.
