Specifications of MAX1747EVKIT

Lead Free Status / RoHS Status
Lead free / RoHS Compliant
The MAX1747 evaluation kit (EV kit) is a fully assembled
and tested surface-mount circuit board that contains
three charge-pump regulators. The first one is a high-
current step-up DC-DC converter and is configured for
a +5V output that provides up to 200mA of current. The
other two charge pumps are low-current charge pumps
that generate positive and negative voltages. A +3.0VDC
to +3.6VDC source can be utilized to power the EV kit
input.
The low-current negative charge-pump circuit is config-
ured for a -7V output; the low-current positive charge-
pump circuit is configured for a +12V output. Both cir-
cuits provide up to 20mA of current. The high-current
step-up DC-DC converter or the EV kit’s input source
can be used to power either or both charge pumps.
The MAX1747 EV kit demonstrates an inductorless and
low profile (1.1mm max) solution. Operation up to
1.23MHz allows the use of tiny surface-mount compo-
nents and provides fast transient response.
