Description

This is (MAX17497A/B) AC-DC and DC-DC Peak-Current-Mode Converters. EVALUATION KIT AVAILABLE 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 low-voltage DC-DC applications. Both devices also include a 3.3V fixed-output synchronous step-down regulator that delivers up to 600mA load current. The switching frequency of the MAX17497A flyback converter is 250kHz, while the MAX17497B flyback, boost converter is 500kHz. The internally comp.
