LTC3542EDC#TRMPBF

LTC3542EDC#TRMPBF Description

The LTC3542EDC#TRMPBF from Analog Devices Inc. is a high-efficiency, synchronous step-down DC-DC converter designed for compact, power-sensitive applications. This buck regulator delivers up to 500mA of continuous output current with an adjustable output voltage range of 0.6V to 5.5V, making it highly versatile for low-power systems. Its 2.5V to 5.5V input range supports operation from single-cell Li-ion batteries or regulated 3.3V/5V rails. The device operates at a high 2.25MHz switching frequency, enabling the use of tiny external components and minimizing PCB footprint. Packaged in a 6-pin DFN with tape-and-reel (TR) delivery, it is optimized for surface-mount assembly in space-constrained designs.

LTC3542EDC#TRMPBF Features

• High Efficiency: Synchronous rectification ensures >90% efficiency, reducing power loss and heat dissipation.
• Compact Design: 2.25MHz switching frequency allows for miniature inductors and capacitors.
