TYPICAL APPLICATIONS
FIGURE 14.
A low cost, yet powerful alternative to the single ended converters with parallel MOSFETs is a combination of SG1842 and SG1644
as shown in Figure 16. This combination will also allow a low noise operation by separating the drive and its associated high peak
currents, away from the PWM logic section.
FIGURE 15.
Fast turn off of bipolar transistors is possible by the totem
pose output stage of SG1644. The charge on capacitor C will
drive the base negative for faster turn off.

FIGURE 16.
When the inputs are driven with a TTL square wave drive, the
high peak current capabilites of SG1644 allow easy implem-
entation of charge pump voltage converters.
