Evaluates: MAX17000
Pulse-Skipping Control Input (
SKIP
)
The EV kit features a 2-pin jumper (JU4) for pulse-
skipping control input. This input determines the mode
of operation under normal steady-state conditions and
dynamic output-voltage transitions. See Table 5 for
JU4 functions.
External Reference Input (REFIN)
The EV kit features a 2-pin jumper (JU6) to select the
reference input voltage (REFIN), which regulates the
VTT and VTTR outputs. By default (REFIN connected to
VDD through JU6), the VTT and VTTR outputs track
V
CSL
/2.
To set the adjustable output for VTT and VTTR, remove
the shunt from JU6 and connect an external 0.5V to 1.5V
supply at the REFIN pad. Another adjustable output
option for VTT and VTTR is to install resistors R19 and
R20 with values according to the following equation:
Table 6 summarizes the JU6 functions.
Dual-MOSFET Operation
The MAX17000 EV kit can be evaluated with dual-pack-
age MOSFET N3. To evaluate the kit with a dual-pack-
age MOSFET, remove MOSFETs N1 and N2 and install
N3. Vishay’s Si4916DY is an example of a dual-pack-
age MOSFET that fits the N3 pinout and orientation.
