DESCRIPTION
With power densities up to 25 watts per cubic inch (1.53 watts per
cm
3
), the DSN17 Series delivers 3.5 amperes of current at either
5 or 3.3 volts. Designed for digital and microprocessor applica-
tions, the non-isolated flat package requires only 1 square inch
(6.45 cm
2
) of PCB area. Remote ON/OFF gives additional
system flexibility. The 100KHz operating frequency of the DSN17
Series allows an increased power density while including adequate
heat sinking and input/output filtering. This eliminates the need
for external components in some applications. The Series’ input
range and no load input current (5mA) makes it well suited for
battery operation in commercial and industrial applications. Full
overload protection is provided by pulse-by-pulse current limiting.

NOTES
(1)
All parameters measured at Tc = 25°C, nominal input voltage and full rated load unless otherwise noted.
Refer to the Technical Reference Section for the definition of terms, measurement circuits and other
information.
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 will reduce expected operational life.
The data sheet specifications are not guaranteed beyond the case operating range.
The case thermal impedance is specified as the case temperature rise over ambient per package watt
dissipated.
