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.

With an output voltage range adjustable via I

2C™ 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 VOUT. In hardware shutdown, the current

consumption is reduced to less than 200nA.

The serial interface is compatible with fast / standard mode,

fast mode plus, 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 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.
