XC9280 Datasheet Step-down DC/dc Converter

Manufacturer: Torex Semiconductor

Overview: XC9280 Series 18V Operation 3.0A Synchronous Step-Down DC/DC Converters ETR05064-003.

General Description

The XC9280 series is 18V bootstrap synchronous step-down DC/DC converter with built-in Nch-Nch driver transistors, the operating voltage range is 4.5V~18.0V, designed to allow the use of ceramic capacitors.

0.75V reference voltage source is incorporated in the IC, and the output voltage can be set to a value from 1.8V to 7.0V using external resistors (RFB1, RFB2).

Switching frequency is 1.2MHz.
