XC9291 - 600mA Step-Down DC/DC Converters

Download the XC9291 datasheet PDF. This datasheet also covers the XC9290 variant, as both devices belong to the same 600ma step-down dc/dc converters family and are provided as variant models within a single manufacturer datasheet.

Description

☆Green Operation Compatible The XC9290/XC9291 series are 600mA synchronous rectification DC/DC converters adopting HiSAT-COT (

) control.

increasing the oscillation frequency to high frequency, coil with a size of 0.8 x 0.45 mm can be used.

XC9290/XC9291 Series ETR05089-001d HiSAT-COT ® Control Extremely Small 600mA Step-Down DC/DC Converters ■GENERAL DESCRIPTION ☆Green Operation Compatible The XC9290/XC9291 series are 600mA synchronous rectification DC/DC converters adopting HiSAT-COT (*) control. Due to increasing the oscillation frequency to high frequency, coil with a size of 0.8 x 0.45 mm can be used. A 0.6 x 0.3 mm ceramic capacitor can be used for the input capacitance (CIN) and the output capacitance (CL), realizing that the mounting area including peripheral components can be reduced to 3.15 mm2. Due to increasing the oscillation frequency to a high frequency, the mounting area is reduced.
