XC9142 - 0.8A Step-up DC/DC Converters

Download the XC9142 datasheet PDF. This datasheet also covers the XC9141 variant, as both devices belong to the same 0.8a step-up dc/dc converters family and are provided as variant models within a single manufacturer datasheet.

Description

XC9141/XC9142 series are synchronous step-up DC/DC converters with a 0.3Ω N-channel driver transistor and a 0.3Ω synchronous P-channel switching transistor built-in.

A highly efficient and stable current can be supplied up to 0.8A by reducing ON resistance of the built-in transistors.

XC9141/XC9142 Series ETR04018-003d Load Disconnection Function, 0.8A Step-up DC/DC Converters ☆Green Operation compatible ■GENERAL DESCRIPTION XC9141/XC9142 series are synchronous step-up DC/DC converters with a 0.3Ω N-channel driver transistor and a 0.3Ω synchronous P-channel switching transistor built-in. A highly efficient and stable current can be supplied up to 0.8A by reducing ON resistance of the built-in transistors. The series are able to start operation under the condition which has 0.9V input voltage to generate 3.3V output voltage with a 100Ω load resistor, suitable for mobile equipment using only one Alkaline battery or one Nickel metal hydride battery. The output voltage can be set from 1.8V to 5.5V (±2.0%) in steps of 0.1V. With the built-in oscillator, either 1.2MHz or 3.
