PARAMETER
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.
MAX860/MAX861 may draw high supply current during startup, up to the minimum operating supply voltage. To guaran-
tee proper startup, the input supply must be capable of delivering 90mA more than the maximum load current.
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
