LTC3545EUD#TRPBF Description

Short technical summary and product information.

The LTC3545/LTC3545-1 from LT are triple, high-efficiency, monolithic synchronous buck regulators. They utilize a constant frequency, current mode architecture and operate independently with separate run pins. The input voltage range of 2.25V to 5.5V makes them suitable for single Li-Ion battery-powered applications.

 

These regulators feature a switching frequency internally set to 2.25MHz, which can also be synchronized to an external clock between 1MHz and 3MHz. They offer externally selectable low ripple pulse skip mode or high efficiency Burst Mode operation. The internal synchronous switches enhance efficiency and eliminate the need for external Schottky diodes. Power good indicators are included to facilitate power sequencing between the three regulators.

 

The LTC3545EUD#TRPBF is available in a low profile 16-lead 3mm x 3mm QFN package, suitable for surface mount applications. The 0.6V feedback reference voltage supports low output voltages, and the device offers up to 95% efficiency. Quiescent current is as low as 58μA.
