DESCRIPTION
The MP1517 is a 3A, fixed frequency step-up converter ideal for medium-to-high current step-up, flyback and SEPIC applications. The high 1.1MHz switching frequency allows for smaller external components producing a compact solution for size constrained cameras, PDAs and cell phones. The low 0.7V feedback voltage offers higher efficiency in white LED driver applications including cell phone camera flash.
