Applications Information
1-Cell and 2-Cell Circuits
See Figure 3 for an illustration of how to power the
MAX5532–MAX5535 with either one lithium-ion battery
or two alkaline batteries. The low current consumption
of the devices make the MAX5532–MAX5535 ideal for
battery-powered applications.
Programmable Current Source
See the circuit in Figure 4 for an illustration of how to
configure the MAX5534/MAX5535 as a programmable
current source for driving an LED. The MAX5534/
MAX5535 drive a standard NPN transistor to program
the current source. The current source (ILED) is defined
in the equation in Figure 4.
