NOTES
*
All parameters measured at Tc = 25°C, nominal input voltage
and full rated load unless otherwise noted. Refer to the
CALEX Application Notes for the definition of terms,
measurement circuits and other information.
Noise is measured per CALEX application notes. Measurement
bandwidth is 0-20 MHz. RMS noise is measured over a 0.01-1
MHz bandwidth. To simulate standard PCB decoupling practices,
output noise is measured with a 10μf tantalum and 0.01μF
ceramic capacitor located 1 inch away from the converter. Input
ripple is measured into a 10μH source impedance.
See our application note for picking the correct fuse size.
Transient response is specified for a 50 to 75% step load
change. Rise time of step is 2 microseconds.
Dynamic response is the peak overshoot for a transient as
described in note 3.

Input ripple rejection is specified for a DC to 120 Hz ripple with
a modulation amplitude of 1% of Vin or less.
The functional temperature range is intended to give an additional
data point for use in evaluating this power supply. At the
low functional temperature the power supply will function with
no side effects, however sustained operation at the high
functional temperature may reduce the expected operational
life. The data sheet specifications are not guaranteed over
the functional temperature range.
The case thermal impedance is specified as the case temperature
rise over ambient per package watt dissipated.
See power/voltage derating curves.
No harm when operated at less than maximum load. See section
on Operation with Light Loads.
(10) Specifications subject to change without notice.
