TCV7108FN

Buck DC-DC Converter IC

The TCV7108FN is a single-chip buck DC-DC converter IC.

The TCV7108FN contains high-speed and low-on-resistance power

MOSFETs for the main switch and synchronous rectifier to achieve

high efficiency.

The TCV7108FN is a product that improves the load response

characteristic of TCV7104FN.

Features

 High efficiency:   95% (typ.)

 Uses internal phase compensation to achieve high efficiency and high load response characteristic with a

minimum of external components.

 Allows the use of a small surface-mount ceramic capacitor as an output filter capacitor and the high load

response characteristic is obtained by the capacity value of 40μF.

 Housed in a small surface-mount package (PS-8) with a low thermal resistance.

 Soft-start time adjustable by an external capacitor

Pin Assignment

This product has a MOS structure and is sensitive to electrostatic discharge. Handle with care.

The product(s) in this document (“Product”) contain functions intended to protect the Product from temporary

small overloads such as minor short-term overcurrent, or overheating. The protective functions do not necessarily

protect Product under all circumstances. When incorporating Product into your system, please design the system (1)

to avoid such overloads upon the Product, and (2) to shut down or otherwise relieve the Product of such overload

conditions immediately upon occurrence. For details, please refer to the notes appearing below in this document and

other documents referenced in this document.
