The choice of external components is primarily dictated
by output voltage, maximum load current, and maxi-
mum and minimum input voltages. Begin by selecting
an inductor value. Once the inductance is known,
choose the diode and capacitors.
Inductor Selection
Applications Information
Step-up regulators using the MAX17112 can be
designed by performing simple calculations for a first
iteration. All designs should be prototyped and tested
prior to production. Table 1 provides a list of power
components for the typical applications circuit. Table 2
lists component suppliers.
The minimum inductance value, peak current rating,
and series resistance are factors to consider when
selecting the inductor. These factors influence the con-
verter’s efficiency, maximum output load capability,
transient response time, and output voltage ripple.
Physical size and cost are also important factors to be
considered.
