between 1.8V and 5.5V. It uses a pulse-frequency-  
modulation (PFM) control scheme to generate the regulat-  
ed negative output voltage. PFM operation is obtained  
by gating the internal 450kHz oscillator on and off as  
ne e d e d to ma inta in outp ut volta g e re g ula tion. This  
unique on-demand switching scheme gives the MAX868  
excellent light-load efficiency without degrading its full-  
load operation (up to 30mA), permitting smaller capaci-  
tors to take advantage of the oscillators high switching  
frequency.  
The MAX868 requires no inductors; only four capacitors  
are required to build a complete DC-DC converter.  
Output voltage regulation is achieved by adding just two  
resistors. The MAX868 comes in a 10-pin µMAX pack-  
age, which is only 1.11mm high and occupies just half  
the board area of a standard 8-pin SO.
