Synchronous Step-Down Switching Regulator
DESCRIPTIO
The LTC
廬
1709-7 is a 2-phase, VID programmable, synchro-
nous step-down switching regulator controller that drives
two all N-channel external power MOSFET stages in a fixed
frequency architecture. The 2-phase controller drives its two
output stages out of phase at frequencies up to 300kHz to
minimize the RMS ripple currents in both input and output
capacitors. The 2-phase technique effectively multiplies the
fundamental frequency by two, improving transient re-
sponse while operating each channel at an optimum fre-
quency for efficiency. Thermal design is also simplified.
An operating mode select pin (FCB) can be used to regu-
late a secondary winding or select among three modes
including Burst Mode
TM
operation for highest efficiency. An
internal differential amplifier provides true remote sensing
of the regulated supply鈥檚 positive and negative output ter-
minals as required in high current applications.
The RUN/SS pin provides soft-start and optional timed,
short-circuit shutdown. Current foldback limits MOSFET
dissipation during short-circuit conditions when the
overcurrent latchoff is disabled. OPTI-LOOP compensation
allows the transient response to be optimized for a wide
range of output capacitors and ESR values.
