XC9148 Datasheet 1.4a Step-up DC/dc Converters

Manufacturer: Torex Semiconductor

Overview: XC9147/XC9148 Series ETR04028-004b Highly functionality, 1.4A Step-up DC/DC Converters ☆Green Operation compatible.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

XC9147/XC9148 series are synchronous step-up DC/DC converters with a 0.17Ω Nch driver FET and a 0.2Ω synchronous Pch switching FET built-in.

The series are able to start operation from an input voltage of 0.9V, suitable for equipment using single Alkaline battery or Nickel metal hydride battery.

The output voltage can be set from 1.8V to 5.5V in steps of 0.1V.
