5 to 7.5 Watt FW Single Series DC/DC Converters
Description
Features
!
The low voltage FW single output converters are designed for
ultra wide input range, low noise industrial and instrument
applications requiring low input operating voltages. The wide
input range (3:1) is ideal for battery or unregulated input
applications.
Low noise outputs, 70 mV P-P maximum
!
Very low reflected ripple, 50 mA P-P maximum
!
Excellent regulation from no load to full load 0.2%
maximum
These converters are state-of-the-art 100 kHz designs that
provide outstanding line and load regulation with efficiencies
approaching 82%.
!
Excellent line regulation, 0.1% maximum
!
Efficiencies to 82%
!
The single outputs are regulated with a high loop gain
current mode control method that provides linear regulator
typeperformancewithatrue, highefficiencyswitchingDC/DC
topology. The large amount of loop gain also insures excellent
input ripple rejection and line transient response.
Six-sided shielded low thermal gradient copper case

All converters in this series are protected from output short
circuit, thermal overload and overvoltage transients on the
input and output.

NOTES:
All Parameters measured at Tc=25°C, nominal input voltage

CALEX Application Notes for the definition of terms,
measurement circuits and other information.
(7) Dynamic response is the peak overshoot during a transient as
defined in note 6.

(8) The input ripple rejection is specified for DC to 120 Hz ripple with
a modulation amplitude of 1% of Vin.
(2) Noise is measured per CALEX Application Notes. Measurement
bandwidth is 0-20 MHz.
(9) For module protection only, see note 3.
(10) Thefunctionaltemperaturerangeisintendedtogiveanadditional
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 over the functional
temperature range.
