MAX17498B - AC-DC and DC-DC Peak-Current-Mode Converters

Download the MAX17498B datasheet PDF. This datasheet also covers the MAX17498A variant, as both devices belong to the same ac-dc and dc-dc peak-current-mode converters family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX17498A/MAX17498B/MAX17498C devices are current-mode fixed-frequency flyback/boost converters with a minimum number of external components.

They contain all the control circuitry required to design wide input voltage isolated and nonisolated power supplies.

Key Features

  • S Peak Current-Mode Converter S Current-Mode Control Provides Excellent Transient Response S Fixed Switching Frequency.

EVALUATION KIT AVAILABLE MAX17498A/MAX17498B/MAX17498C AC-DC and DC-DC Peak Current-Mode Converters for Flyback/Boost Applications General Description The MAX17498A/MAX17498B/MAX17498C devices are current-mode fixed-frequency flyback/boost converters with a minimum number of external components. They contain all the control circuitry required to design wide input voltage isolated and nonisolated power supplies. The MAX17498A has its rising/falling undervoltage lockout (UVLO) thresholds optimized for universal offline (85V AC to 265V AC) applications, while the MAX17498B/ MAX17498C support UVLO thresholds suitable to lowvoltage DC-DC applications. The switching frequency of the MAX17498A/MAX17498C is 250kHz, while that of the MAX17498B is 500kHz.
