MAX17497B Datasheet AC-dc And DC-dc Peak-current-mode Converters

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: EVALUATION KIT AVAILABLE MAX17497A/MAX17497B AC-DC and DC-DC Peak Current-Mode Converters with Integrated Step-Down Regulator.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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.
