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
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.
