MAX17497A/MAX17497B
AC-DC and DC-DC Peak Current-Mode Converters with Integrated Step-Down
Regulator
General Description
The MAX17497A/MAX17497B include both a currentmode fixed-frequency flyback converter and a synchronous step-down
regulator.
They contain all the control circuitry required to design wide input-voltage nonisolated power supplies to supply multiple output rails for smart meters, industrial control, and other similar applications.
The MAX17497A has its rising/falling undervoltage lockout (UVLO) thresholds optimized for universal offline (85V AC to 265V AC) applications, while the MAX17497B supports undervoltage lockout (UVLO) thresholds suitable to...
