The CXSU63141 is a synchronous rectifier, fixed switching frequency (1MHz typical), and current-mode step-up regulator. The device allows use of small inductors and output capacitors for portable devices. The current-mode control scheme provides fast transient response and good output voltage accuracy   

At light loads, the CXSU63141 will automatically enter in pulse frequency modulation(PFM) operation to reduce the dominant switching losses. During PFM operation, the IC consumes very low quiescent current and maintains high efficiency over the complete load range. The device has a 1.05V start-up voltage and can operate with input voltage down to 0.8V after start-up The CXSU63141 also includes current-limit and over-temperature shutdown to prevent damage in the event of an output overload. The CXSU63141 is available in 2mmx2mm TDFN2x2-8 and TSOT-23-6A packages.
