The XC9101 series are step-up multiple current and voltage feedback
DC/DC controller ICs. Current sense, clock frequencies and amp
feedback gain can all be externally regulated.
A stable power supply is possible with output currents of up to 1.5A.
With output voltage fixed internally, V
OUT
is selectable in 0.1V steps
within a 2.5V - 16.0V range (± 2.5%).
For output voltages outside this range, we recommend the FB version
which has a 0.9V internal reference voltage. Using this version, the
required output voltage can be set-up using 2 external resistors.
Switching frequencies can also be set-up externally within a range of
100~600 kHz and therefore frequencies suited to your particular
application can be selected.
With the current sense function, peak currents (which flow through
the driver transistor and the coil) can be controlled. Soft-start time can
be adjusted using external resistor and capacitor.
During shutdown (CE pin =L), consumption current can be reduced to
as little as 0.5
μ
A (TYP.) or less.
