Capacitor selection
A ceramic capacitor grounded close to the GND pin of
the package is recommended at the output of the
device. S urface mount types offer the best
performance due to their lower inductance. A
minimum value of 0.22
μ
F is advised, although higher
values will lower switching frequency and improve
efficiency especially at lower load currents. A higher
value will also minimize ripple when using the device
to provide an adjustable dc output current.
A good quality, low ESR capacitor should also be used
for input decoupling, as the ESR of this capacitor is
effectively in series with the source impedance and
lowers overall efficiency. This capacitor has to supply
the relatively high peak current to the coil and smooth
the current ripple on the input supply. A minimum
value of 4.7
μ
F is acceptable if the input source is close
to the device, but higher values will improve
performance at lower input voltages, when the source
impedance is high. The input capacitor should be
mounted as close as possible to the IC
Inductor selection
The choice of inductor will depend on available board
space as well as required performance. Small value
inductors have the advantage of smaller physical size
and may offer lower series resistance and higher
saturation current compared to larger values. A
disadvantage of lower inductor values is that they
result in higher frequency switching, which in turn
causes reduced efficiency due to switch losses. Higher
inductor values can provide better performance at
lower supply voltages. However, if the inductance is
too high, the output power will be limited by the
internal oscillator, which will prevent the coil current
from reaching its peak value. This condition will arise
whenever the ramp time (I
x L/V
) exceeds the
nominal5

s maximum ‘on’ timelimitfortheLX output.

Recommended inductor values for the ZXLD1601 are
in the range 6.8
μ
H to 22
μ
H. The inductor should be
mounted as close to the device as possible with low
resistance connections to the LX and VIN pins.
