About This Product

■Summary

The MP1517 is a 3A fixed frequency step-up converter ideal for medium to high current step-up, flyback, and SEPIC applications. A high switching frequency of 1.1MHz allows for small external components, enabling compact solutions for size-constrained cameras, PDAs, and mobile phones. The low 0.7V feedback voltage improves efficiency in white LED driver applications such as cell phone camera flashes. The MP1517 regulates output voltages up to 25V with 95% efficiency. Soft-start, cycle-by-cycle current limit, and input undervoltage lockout prevent undue stress or damage to sensitive external circuitry during start-up and output short-circuit conditions. Current-mode regulation and external compensation components allow the MP1517's control loop to be optimized over various input voltage, output voltage, and load current conditions. The MP1517 is available in a thermally enhanced QFN16 (4mm x 4mm) package.

■Features and benefits
