MAX16920B Evaluation Kit
Evaluates: MAX16920A/MAX16920B
LDOA
The output voltage on the linear regulator (LDOA) is set
at 5V and can be accessed from the OUTA PCB pad on
the EV kit. The output can be enabled or disabled by
placing a shunt in the appropriate position on jumper JU3
(see Table 1). To enable LDOA, place a shunt in the 1-2
position on JU3. To disable LDOA, place a shunt in the
2-3 position on JU3. LED D3 indicates that the output of
LDOA is in the correct regulation range.
SYNC
The IC provides a fixed 2.2MHz switching frequency
when the SYNC PCB pad on the EV kit is connected
to ground. For external synchronization, apply a clock
signal between 1.8MHz to 2.4MHz at the SYNC PCB pad
on the EV kit.
Voltage Output (UVO)
UVO is an active-low voltage output to monitor the input
voltage and is accessible through the UVOB PCB pad on
the EV kit. The UVO signal is pulled low by the IC when
the V
IN
falls below 7V.
Overtemperature Output (OT)
OT is an active-low overtemperature output and is
accessible through the OTB PCB pad on the EV kit. The
OT signal is pulled low by the IC and disables all convert-
ers except for DC-DC1 if the die temperature exceeds the
thermal-shutdown temperature.
Evaluating the MAX16920A
Included with the EV kit are capacitors and inductors to
evaluate the MAX16920A. Replace C10, C11, and C12
with the 22FF capacitors, C20 with the 47FF capacitor, L1
with the 47FH inductor, L2 with the 22FH inductor, and L3
with the 10FH inductor.
