The CXSU63278 is a high-power, fully integrated boost converter with an integrated 16mΩ power switch and 23mΩ synchronous rectifier to provide an efficient and small solution for portable systems. The CXSU63278 has a wide input voltage range of 2.7V to 13V to support applications with single or two-cell lithium batteries. The device has a 10A switching current capability and can provide an output voltage of 13V. CXSU63278 adaptive constant off-time peak current control topology is used to regulate the output voltage. Under moderate to heavy load conditions, the CXSU63278 operates in PWM mode. Under light load conditions, the device operates in a PFM mode that improves efficiency. In addition, the device provides 14V output overvoltage protection, cycle-by-cycle overcurrent protection and thermal shutdown protection.
