Torex Semiconductor XC9290/XC9291 Step-Down DC/DC Converters
Torex XC9290 / XC9291 Step-down DC/DC Converters feature HiSAT-COT® control and a synchronous rectification buck DC/DC converter. The XC9290 / XC9291 devices offer a small 3.52mm2 mounting area, high-speed response, and ultra-low radiation noise. Using HiSAT-COT, Torex XC9290 / XC9291 Step-down DC/DC Converters provide faster response than PWM control methods, which allows for a reduced capacitor size with stable operation. The converters have an ultra-compact layout and improved oscillation frequency for greater user control. The converters feature an extended battery life, reduced heat generation, and are ideal for consumer and industrial applications.Features
