Applications Information
IN Bypass Capacitor
For most applications, bypass IN to GND with a 0.1µF
ceramic capacitor as close as possible to the device. If
the power source has significant inductance due to long
lead length, the device clamps the overshoot due to LC
tank circuit.

OUT Output Capacitor
The slow turn-on time provides a soft-start function that
allows the MAX14653/MAX14654/MAX14655 to charge
an output capacitor up to 1000µF without turning off due
to an overcurrent condition.
External OVLO Adjustment Functionality
If OVLO is connected to ground, the internal OVLO com-
parator uses the internally set OVLO value.
If an external resistor-divider is connected to OVLO
and V

fraction fixed by the external resistor divider. R
a good starting value for minimum current consumption.
Since V

This external resistor-divider is completely independent
from the internal resistor-divider.
ESD Test Conditions
ESD performance depends on a number of conditions.
The MAX14653/MAX14654/MAX14655 are specified for
±2kV HBM typical ESD on all pins, Contact and Air-Gap
Discharge on pin IN. Contact Maxim for a reliability report
that documents test setup, test methodology, and test
results.
HBM ESD Protection
Figure 2a
shows the current waveform it generates when discharged
into low impedance. This model consists of a 100pF
capacitor charged to the ESD voltage of interest, which is
then discharged into the device through a 1.5kΩ resistor.
