Overview
Description
Key features include its ability to operate with input voltages ranging from 4V to 60V, with a high-efficiency synchronous rectification and low quiescent current. This makes it suitable for battery-powered applications as well. The controller supports three independent outputs which can be configured for different output voltages and currents. It also includes features such as programmable frequency, synchronization capability, and adjustable current limit, enhancing design flexibility.
The LTC3859AEFE#TRPBF is designed to drive external N-channel MOSFETs, and it includes protection features like overload protection, soft-start, and short-circuit protection. The package type for this part is TSSOP-38 with exposed pads for improved thermal performance.
Features
The controller is capable of driving external N-channel MOSFETs and supports output voltages as low as 0.8V. It offers a programmable switching frequency from 50kHz to 900kHz, enabling optimization between efficiency and component size. The LTC3859AEFE#TRPBF includes features like programmable current limit, soft-start, and tracking, enhancing its flexibility and reliability in different design scenarios.
Additional features include an adjustable and precise current limit, a power good output voltage monitor, and strong line and load regulation. Its robust design includes short-circuit protection and thermal shutdown, ensuring safety under fault conditions. The device is housed in a thermally enhanced 28-lead TSSOP package, making it suitable for compact and constrained environments.
