The CXSU63217 is a monolithic high voltage switching regulator with integrated 1.1A, 40V power MOSFET. It can be configured in several standard switching-regulator topologies, including boost and SEPIC converter. The device has a wide input voltage range to support applications with input voltage from multi-cell batteries or regulated 5V, 12V power rails.
The CXSU63217 uses a 1.2MHz switching frequency, allowing the use low-profile inductors and low-value ceramic input and output capacitors. The external loop compensation gives the user flexibility to optimize loop compensation and transient response. The device has built-in protection features, such as cycle-by-cycle over-current limit, output OVP, soft-start and thermal shutdown.
