XC9129 Datasheet Step-up DC/dc Converters

Manufacturer: Torex Semiconductor

Overview: XC9128/XC9129 Series 1A Driver Transistor Built-In, Step-Up DC/DC Converters ETR0411-012 ☆Green Operation patible.

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

General Description

The XC9128/XC9129 series are synchronous step-up DC/DC converters with a 0.2Ω (TYP.) N-channel driver transistor and a synchronous 0.2Ω (TYP.) P-channel switching transistor built-in.

A highly efficient and stable current can be supplied up to 1.0A by reducing ON resistance of the built-in transistors.

With a high switching frequency of 1.2MHz, a small inductor is selectable making the series ideally suited for applications requiring low profile or space saving solutions.
