LTC3545EUD#TRPBF Description

Short technical summary and product information.

The LTC3545EUD#TRPBF from Analog Devices is a highly efficient, monolithic triple synchronous buck regulator. It utilizes a constant frequency, current mode architecture and operates independently with separate run pins. The device is well-suited for single Li-Ion battery-powered applications due to its 2.25V to 5.5V input voltage range.

 

Key electrical specifications include three 800mA outputs, a switching frequency internally set to 2.25MHz, and a low output ripple of less than 20mVP-P in Burst Mode operation. The regulators offer high efficiency up to 95% and support low output voltages with a 0.6V feedback reference voltage. Power good indicators are included to ease supply sequencing.

 

This regulator is available in a low profile 16-lead 3mm x 3mm QFN package, suitable for surface mount applications. Its design makes it ideal for point-of-load regulation in portable instruments, smart phones, and wireless modems.
