Description
The FAN5365 is a high-frequency, ultra-fast transient
response, synchronous step-down, DC-DC converter
optimized for low-power applications using small, low-cost
inductors and capacitors. The FAN5365 supports up to
800mA or 1A load current.
The FAN5365 is ideal for mobile phones and similar portable
applications powered by a single-cell Lithium-Ion battery.
2
With an output voltage range adjustable via I C™ interface
from 0.75V to 1.975V, it supports low-voltage DSPs and
processors, core power supplies, and memory modules in
smart phones, data cards, and hand-held computers.
The FAN5365 operates at 6MHz (nominal) fixed switching
frequency in PWM mode.
During light-load conditions, the regulator includes a PFM
mode to enhance light-load efficiency. The regulator
transitions smoothly between PWM and PFM modes with no
glitches on V
OUT
. In hardware shutdown, the current
consumption is reduced to less than 200nA.
The serial interface is compatible with fast / standard mode,
2
fast mode plus, and high-speed mode I C specifications,
allowing transfers up to 3.4Mbps. This interface is used for
dynamic voltage scaling with 12.5mV voltage steps, for
reprogramming the mode of operation (PFM or forced
PWM), or to disable/enable the output voltage.
The chip's advanced protection features include short-circuit
protection and current and temperature limits. During a
sustained over-current event, the IC shuts down and restarts
after a delay to reduce average power dissipation into a
fault.
During startup, the IC controls the output slew rate to
minimize input current and output overshoot at the end of
soft-start. The IC maintains a consistent soft-start ramp,
regardless of output load during startup.
The FAN5365 is available in a 1.27 x 1.29mm, 9-bump
WLCSP package.
