1 / 14 page  MP1527 2A, 1.3MHz Step-Up Converter MP1527 Rev 1.8_8/31/05 Monolithic Power Systems, Inc. 1 Monolithic Power Systems General Description The MP1527 is a 2A, fixed frequency step-up converter in a tiny 16 lead QFN package. The high 1.3MHz switching frequency allows for smaller external components producing a compact solution for medium-to-high current step-up, flyback, and SEPIC applications. The MP1527 regulates the output voltage up to 25V at efficiency as high as 93%. Soft-start, timer-latch fault circuitry, cycle-by-cycle current limiting, and input undervoltage lockout prevent overstressing or damage to external circuitry at startup and output short-circuit conditions. Fixed frequency operation eases control of noise making the MP1527 optimal for noise sensitive applications such as mobile handsets and wireless LAN PC cards. Current-mode regulation and external compensation components allow the MP1527 control loop to be optimized over wide variety of input voltage, output voltage and load current conditions. The MP1527 is offered in a tiny 4mm x 4mm 16 lead QFN and 14 lead TSSOP packages.
