MAX17595ATE+T

MAX17595 is a peak-current-mode controller for design of wide input-voltage flyback and boost regulator. It offers optimized input thresholds for universal input AC-DC converters and telecom DC-DC power supplies. It houses an internal error amplifier with 1% accurate reference, eliminating the need for an external reference. The switching frequency is programmable from 100KHz to 1MHz with an accuracy of 8%, allowing optimization of magnetic and filter components, resulting in compact and cost-effective power conversion. For EMI-sensitive applications, the family incorporates a programmable frequency dithering scheme, enabling low-EMI spread-spectrum operation. Users can start the power supply precisely at the desired input voltage, implement input overvoltage protection, and program soft-start time. Application includes universal input offline AC-DC power supplies, wide-range DC-input flyback/boost battery chargers, battery-powered applications, industrial and telecom applications.
