Beschreibung
The MAX17598/MAX17599 low IQ, active clamp current-mode PWM controllers contain all the control circuitry required for the design of wide-input isolated/non-isolated forward-converter industrial power supplies. The MAX17598 is well-suited for universal input (rectified 85V AC to 265V AC) or telecom (36V DC to 72V DC) power supplies. The MAX17599 is optimized for low-voltage industrial supplies (4.5V DC to 36V DC).
