The MAX17497A/MAX17497B include both a currentmodefixed-frequency PWM converter and a synchronousstep-down regulator. They contain all the controlcircuitry required to design wide-input-voltage nonisolatedpower supplies to supply multiple output rails forsmart meters, industrial control, and other similar applications.The MAX17497A has its rising/falling undervoltagelockout (UVLO) thresholds optimized for universal offline(85V AC to 265V AC) applications, while the MAX17497Bsupports undervoltage lockout (UVLO) thresholds suitableto low-voltage DC-DC applications. Both devicesalso include a 3.3V fixed-output synchronous step-downregulator that delivers up to 600mA load current.
