Specifications of MAX15008EVKIT+

• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

Note: The overvoltage protector does not provide cur-
rent-limiting protection. Verify that the IN2 input supply
current is limited, according to the OUT_PROTECT
load, and that the current ripple rating of capacitors C7
and C11, which is recommended for separate power
operation, is not exceeded.
The overvoltage protector can be enabled or disabled
by configuring jumper JU4. See Table 3 for jumper JU4
configuration.

The MAX15008 EV kit features output signal RESET for
monitoring output OUT_LDO. The RESET output is
asserted high (OUT_LDO voltage) when output
OUT_LDO exceeds the voltage threshold of 92.5% of
the programmed output voltage for the configured time-
out period (t

MAX15008 Evaluation Kit
The MAX15008 EV kit PCB can be used to evaluate the
MAX15009, MAX15010, or MAX15011 ICs. Remove the
MAX15008 IC (U1) and replace it with any of the three
ICs. The MAX15010 IC integrates the same functions as
the MAX15008 minus the overvoltage protector. The
MAX15009 IC integrates an LDO, a switched output, and
an overvoltage protector. The MAX15011 IC integrates
the same functions as the MAX15009, minus the over-
voltage protector. When evaluating the MAX15009 or
MAX15011 ICs, components C8, C10, and R12 must be
installed. Refer to the MAX15008/MAX15010 or the
MAX15009/MAX15011 IC data sheets for a complete
description of part-to-part differences and configuration.
When evaluating the MAX15010 or MAX15011, it is rec-
ommended either to cut the trace connecting the IN
PCB pad to the IN2 PCB pad (drain of MOSFET N1), or
to connect the gate of N1 to ground by installing a low-
value (0603 size) resistor across the C9 PCB pads.
Also, remove resistor R9 to prevent current leakage
from the IN input.
