Description
The FAN49103 is a high efficiency buck-boost switching
mode regulator which accepts input voltages either
above or below the regulated output voltage. Using full-
bridge architecture with synchronous rectification, the
FAN49103 is capable of delivering up to 2.5 A while
regulating the output at 3.4 V. The FAN49103 exhibits
seamless transition between step-up and step-down
modes reducing output disturbances. The output voltage
and
operation
mode
of
the
regulator
can
be
programmed through an I
2C interface.
At
moderate
and
light
loads,
Pulse
Frequency
Modulation (PFM) is used to operate the device in
power-save mode to maintain high efficiency. In PFM
mode, the part still exhibits excellent transient response
during load steps. At moderate to heavier loads or
Forced PWM mode, the regulator switches to PWM
fixed-frequency control. While in PWM mode, the
regulator operates at a nominal fixed frequency of
1.8 MHz, which allows for reduced external component
values.
