Overview

...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.
These frequencies allow the use of tiny magnetic and filter c...
