Figure 3 shows the MAX17579 switching regulator IC, which generates
a negative voltage from a positive voltage. As can be seen in Figure
3, the circuit is much more compact than the one in Figure 2.
Simulation tools such as LTspice
®
or the EE-SIM
®
design and
evaluation environment can provide a better understanding of
the regulation behavior and potential differences in an inverting
topology. These tools can also be used to design and optimize
level shift circuits. The EE-SIM design tool also easily simulates ICs
like the MAX17579.
