The CXSU63275 is a high-power, fully-integrated boost converter with a gate drive with load shutdown, integrated 16mΩ power switch and 16mΩ synchronous rectifier, providing an efficient and small solution for portable systems. The CXSU63275 has a wide input voltage range of 2.7V to 20V, which can support applications using single or two-cell lithium batteries, or 12V lead-acid batteries. The device has 14A switch current capability and can provide up to 20V output voltage. CXSU63275 adaptive constant off-time peak current control topology is used to regulate the output voltage. Under moderate to heavy load conditions, the CXSU63275 operates in PWM mode. Under light load conditions, the device can select one of two modes of operation via the MODE pin. One is a PFM mode that can improve efficiency; the other is a forced PWM mode that can avoid application problems caused by low switching frequency. In PWM mode, the switching frequency of the CXSU63275 can be adjusted by an external resistor, supporting a range of 200kHz to 1.4MHz. The CXSU63275 also supports programmable soft-start and adjustable switching peak current limit. In addition, CXSU63275 the gate drive integrated with the output shutdown function, the input power can be completely disconnected in the SD state. In addition, the device offers 22V output overvoltage protection, cycle-by-cycle overcurrent protection, and thermal shutdown protection
