Quick Start
Detailed Description of Hardware
The MAX17579EVKIT# and MAX17580EVKIT# EV kits are
designed to demonstrate the salient features of MAX17579
and MAX17580 devices, respectively. These two circuits
are electrically isolated from each other and hosted on
the same PCB. Each of the devices can be evaluated by
powering them from their respective input pins. Individual
device settings can be adjusted to evaluate their perfor-
mance under different operating conditions.
Recommended Equipment
● MAX17579EVKIT#, MAX17580EVKIT#
● 60V, 0.5A DC input power supply
● 5V, 10mA DC input power supply
● Loads capable of sinking 300mA at -5V and 240mA
at -15V
● Two digital multimeters (DMM)
Soft-Start Input (SS)
Equipment Setup and Test Procedure
The EV kits are fully assembled and tested.
The EV kits offer an adjustable soft-start function to limit
inrush current during startup. The soft-start time is adjust-
ed by the value of external soft-start capacitor connected
between SS and SOUT pins. The selected output capaci-

1) Set the 60V input power supply at 15V for MAX-
17579EVKIT# and MAX17580EVKIT#. Disable the
power supply.
2) Connect the positive terminal of the 60V power sup-
ply to the VIN PCB pad and the negative terminal to
the nearest GND PCB pad.
3) Connect the positive terminal of the 5V power supply
to the respective VEXT PCB pad and the negative
terminal to the nearest GND PCB pad. Set the volt-
age at 5V.
4) Connect the positive terminal of the corresponding
load to the respective GND PCB pad and the nega-
tive terminal to the nearest VOUT PCB pad.
5) Connect one DMM across the respective VOUT PCB
pad and the nearest GND PCB pad, and the another

For example, to program a 1ms soft-start time, a 5600pF
capacitor should be connected from the SS pin to SOUT.
Enable/Undervoltage-Lockout (EN/UVLO)
Programming
The MAX17579 and MAX17580 offer an enable and
adjustable input UVLO feature. In these EV kits, for nor-
mal operation, leave the EN/UVLO jumpers (J101, J201)
open. When jumpers are left open, the MAX17579 and
MAX17580 are enabled when the input voltage rises
above 15.7V. To disable the devices, install shunts across
pins 2–3 on the jumpers (J101, J201). See Table 1 for
jumper (J101, J201) settings. The EN/UVLO PCB pad on
the EV kits support external Enable/Disable control of the
device. Leave the jumpers open when external Enable/

.
9) Observe that both the DMMs display 0V.
10) Increase the input voltage to be above 16V or higher,
which is above the EN/UVLO rising threshold.
11) Verify that the DMM across the output terminal
displays -15V for MAX17579EVKIT# or -5V for
MAX17580EVKIT#.

Applications
External Clock Synchronization (RT/SYNC)
Hot Plug-In and Long Input Cables
The EV kits provide RT/SYNC PCB pads to synchronize
the MAX17579 and MAX17580 to an optional external
clock. The external synchronization clock frequency must
The MAX17579EVKIT# and MAX17580EVKIT# PCB lay-
outs provide optional electrolytic capacitors (C108 = C208
= 22μF/80V). These capacitors limit the peak voltage at
the input of the corresponding device when the DC input
source is Hot-Plugged to the EV kit input terminals with
input cables. The equivalent series resistance (ESR) of
the electrolytic capacitors dampen the oscillations caused
by interaction of the inductance of the input cables, and
the ceramic capacitors at the converters input.

switching frequency programmed by the resistors (R105
and R205) connected to the RT/SYNC pin. For more
details about the External Clock Synchronization, refer to
the MAX17579, MAX17580 IC data sheet.
Active-Low, Open-Drain Reset
Output (RESET)
Inductive Output Short-Circuit Protection
The EV kits provide two PCB pads RESET1 and RESET2
to monitor the status of the respective converters. The
open-drain outputs are connected to 5V external power
supply (VEXT1, VEXT2) via pullup resistors (R106,
R206). RESET goes high 1024 switching cycles after the
output voltage rises above 95% (typ) of its set value and
it is driven low to respective GND when the output voltage
drops below 92% (typ) of its set value.
The MAX17579EVKIT# and MAX17580EVKIT# PCB
layouts provide footprints for optional R-D circuits (R107
and D101, R207 and D201) that are used for Inductive
Output Short-Circuit Protection. For more details, refer to
the MAX17579, MAX17580 IC data sheet.
Electromagnetic Interference (EMI)
Compliance to conducted emissions (CE) standards
requires an EMI filter at the input of a switching power
converter. The EMI filter attenuates high-frequency cur-
rents drawn by the switching power converter and limits
the noise injected back into the input power source.
Input Voltage Range
The MAX17579EVKIT# and MAX17580EVKIT# has a
default input voltage range starting from 16V. The oper-
ating input voltage range can be modified by changing
the values of the components connected at the FB, EN/
UVLO, and SS pins for the same inductor and output
capacitor. The deliverable output current also changes
with input voltage range. For more details about the Load
Current Capability, refer to the MAX17579, MAX17580
IC data sheet. Table 2 and Table 3 show the settings for
different input voltage ranges for MAX17579EVKIT# and
MAX17580EVKIT#, respectively.
The MAX17579EVKIT# and MAX17580EVKIT# PCBs
have designated footprints for placement of conducted EMI
filter components per the optional Bill of Materials (BoM).
Use of these filter components results in lower conducted
EMI, below CISPR 32 Class B limits. Cut open the trace at
L102 and L202 before installing EMI filter components. The
PCB layouts are also designed to limit radiated emissions
from switching nodes of the power converter, resulting in
radiated emissions below CISPR 32 Class B limits.
