The LTC3546EUFD#TRPBF is a dual, constant-frequency, synchronous step-down DC/DC converter designed for medium power applications by LT. It features configurable 3A/1A or 2A/2A output configurations.
The device supports an input voltage range from 2.3V to 5.5V and offers adjustable output voltages from 0.6V to 5V. The switching frequency can be set to 2.25MHz, adjusted between 0.75MHz and 4MHz, or synchronized to an external clock. Internal synchronous low RDS(ON) power switches contribute to high efficiency, reaching up to 96%, and eliminate the need for external Schottky diodes.
User-selectable modes, including Burst Mode operation, pulse skipping, and forced continuous modes, allow for a trade-off between ripple noise and power efficiency. Burst Mode operation is particularly effective at light loads, providing high efficiency. The regulator is capable of low dropout configurations, allowing both channels to operate at 100% duty cycle. In shutdown mode, the device consumes less than 1µA.
The LTC3546EUFD#TRPBF is available in a thermally enhanced 28-lead (4mm x 5mm) QFN package, suitable for surface mount applications.
The input voltage range is 2.3V to 5.5V.
The output voltage range is 0.6V to 5V.
The maximum efficiency is up to 96%.
The shutdown current is less than 1µA.
It is supplied in a 28-VFQFN Exposed Pad package.
The RoHS status is RoHS3 Compliant.
The Moisture Sensitivity Level is 1 Unlimited.
