Description
The FAN5355 device 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 FAN5355 supports up to
800mA or 1A
(1) load current.
The device is ideal for mobile phones and similar portable
applications powered by a single-cell Lithium-Ion battery. With
an output voltage range adjustable via I
2C™ interface from
0.75V to 1.975V, the device supports low-voltage DSPs and
processors, core power supplies in smart phones, PDAs, and
handheld computers.
The FAN5355 operates at 3MHz (nominal) fixed switching
frequency using either its internal oscillator or external SYNC
frequency.
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 VOUT. Normal PFM (NPFM) mode offers the lowest
quiescent current, at the expense of setpoint accuracy.
Enhanced PFM (EPFM) mode features higher accuracy, as
well as a 25kHz minimum PFM frequency, designed to
prevent the regulator from operating in the audible range. In
shutdown, the current consumption is reduced to less than
2
μA, using software shutdown (EN = 1 with EN_DCDC = 0),
and less than 200nA in hardware shutdown (EN = 0).
The serial interface is compatible with Fast/Standard and
High-Speed mode I
2C 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 start-up, 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 start-up.
The FAN5355 is available in 10-lead MLP (3x3mm) and
12-bump CSP packages.
