XC9271 - 30V Driver Transistor Built-In Step-Down DC/DC Converters

Download the XC9271 datasheet PDF. This datasheet also covers the XC9270 variant, as both devices belong to the same 30v driver transistor built-in step-down dc/dc converters family and are provided as variant models within a single manufacturer datasheet.

Description

The XC9270/XC9271 series are 30V operation step-down DC/DC converter ICs with an internal driver transistor.

The internal Nch driver transistor is driven by bootstrap to achieve a stable, high-efficiency power supply up to an output current of 2.0A.

XC9270/XC9271 Series 30V Driver Transistor Built-In Step-Down DC/DC Converters ETR05048-004a ■GENERAL DESCRIPTION The XC9270/XC9271 series are 30V operation step-down DC/DC converter ICs with an internal driver transistor. The internal Nch driver transistor is driven by bootstrap to achieve a stable, high-efficiency power supply up to an output current of 2.0A. Low ESR capacitors such as ceramic capacitors can be used for the load capacitor (CL). A 0.8V reference voltage source is incorporated in the IC, and the output voltage can be set to a value from 1.2V to 12.0V using external resistors (RFB1, RFB2). 300kHz or 500kHz can be selected for the switching frequency.
