This step-down regulator uses a peak current-mode control scheme to eliminate the additional external compensation required by voltage-mode architectures, providing an easy-to-implement architecture without sacrificing fast transient response. The MAX17083 provides peak current-limit protection and operates in light-load pulse-skipping mode to maintain high efficiency under light-load conditions.
Independent enable input and open-drain power-good output allow flexible system power sequencing. The voltage soft-start gradually ramps up the output voltage within a predictable time period, effectively limiting the inrush current. The MAX17083 features output undervoltage, output overvoltage, and thermal-fault protection.
The MAX17083 is available in a 24-pin 4mm x 4mm x 0.75mm TQFN package. The exposed backside pad improves thermal characteristics.
