JCET CJ92340
The CJ92340 device is an easy-to-use synchronous step-down Buck. The CJ92340 can deliver 4A of output current efficiently with constant on time (COT) control for fast loop response. This CJ92340 device achieves high power conversion efficiency over a wide load range by scaling down the switching frequency under light-load conditions to reduce switching and gate driving losses.| Part No. | CJ92340 |
