MAX3188E/MAX3189E
Applications Information
Power-Supply Sources
The MAX3188E/MAX3189E require ±4.5V to ±6V dual
supplies. For applications where these supply voltages
are not present, a DC-DC converter must be added.
Due to the MAX3188E/MAX3189Es’ low current con-
sumption, a charge pump can provide the proper supply
voltages and requires a minimal amount of board
space and cost.
When using another RS-232 device containing an internal
regulated charge pump (Table 1), the MAX3188E/
MAX3189E may be powered from the internal charge
pump (Figure 6). This eliminates the need for additional
external DC-DC converters to generate the required
±4.5V to ±6V dual supplies.
