Output voltage ripple
Output voltage ripple is shown in Figure 8. The circuit
is operated with a 1.2V input voltage, 3.3V output
voltage and 100mA load current. Output voltage ripple
will be dependent, to a large extent, on the output
capacitor ESR. (see Applications section for
recommended capacitors).

output.
Transient response
Transient response to step changes in load is a critical
feature in many converter circuits. The ZXSC100
operates a pulse by pulse regulation scheme and
therefore corrects for changes in the output every
pulse cycle, giving excellent response characteristic.
Measurement with a power supply
When measuring with a power supply it is important
to realise that the impedance is much greater than that
of a secondary battery (NiCd or NiMH). To simulate the
lower impedance of the battery x10 low ESR 1000uF
capacitors where placed in parallel at the input of the
conv erter.
