Note 2:
C1 and C2 are low-ESR (<0.2
) aluminum electrolytics. Capacitor ESR adds to the circuit’s output resistance. Using
capacitors with higher ESR may reduce output voltage and efficiency.
Specified output resistance includes the effect of the 0.2
ESR of the test circuit’s capacitors.
The switches are driven directly at the oscillator frequency, without any division.
At lowest frequencies, using 10μF capacitors gives worse efficiency figures than using the recommended capacitor
values in Table 3, due to larger 1 (f
s
x C1) term in R
