LTC3785EUF Description

Short technical summary and product information.

The LTC3785EUF is a high-power synchronous buck-boost controller designed to drive all N-channel power MOSFETs. It operates with input voltages ranging from 2.7V to 10V, making it suitable for single or dual cell Li-Ion and multicell alkaline/NiMH applications.

 

Key features include an input and output range of 2.7V to 10V, up to 96% efficiency, and the capability to deliver up to 10A of output current. The controller utilizes an all N-channel MOSFET architecture and does not require a sense resistor (No RSENSE™). It offers true output disconnect during shutdown.

 

The operating frequency is programmable from 100kHz to 1MHz. The soft-start time and current limit are also programmable. Protection features include foldback current limit, short-circuit, and overvoltage protection. The device is available in a 24-lead (4mm x 4mm) exposed pad QFN package.

 

Applications for the LTC3785EUF include palmtop computers, handheld instruments, wireless modems, and cellular telephones.
