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 3.0MHz can

be selected for suiting to your particular application.

During the devices enter stand-by mode, A, D types prevent the application malfunction by C_LDischarge Function which can

quickly discharge the electric charge at the output capacitor (C_L). B, E types is able to drive RTC etc. by Bypass Switch Function

to maintain continuity between the input and output. C, F types is able to connect in output voltage OR circuit with other power

supplies by Load Disconnection Function which breaks continuity between the input and output.
