5 Watt Dual Series DC/DC Converters Features Description ! Low Input/Output Noise Operation ! Low Profile Case (0.38") ! Isolation Capacitance of 50 pF The versatile 5 Watt Dual Output converter is particularly suitable for use in microprocessor systems where 5 Volts is the primary power source, and where a low noise plus and minus output voltage is required. ! Extended Operating Temperature Range of The shielded transformer provides low I/O capacitance and high common mode input to output isolation. -40°C to +100°C. ! Fixed Frequency Operation ! 5 Year Warranty The low guaranteed output noise of 20mV P-P maximum is achieved by a built-in linear post regulator. Available in standard 6 sided shielding, or the -5 model which has 5 sided shielding and is water washable. Each converter is completely specified, fully ATE tested, contains overload protection, and is covered under CALEX’s 5 year warranty.

Refer to the CALEX Application Notes for the definition of terms, measurement circuits and other information. (1) To determine the correct fuse size, see CALEX Application Notes. (2) No minimum load current is required. (3) Short term stability is specified after a 30 minute warm-up at full load, and with constant line, load and ambient conditions. (4) The transient response is specified as the time required to settle from 100% step load change (rise time of step = 2µSec.) to a 1% error band. (5) Dynamic response is the peak overshoot voltage during the (6) (7) (8) transient response time defined in note 4 above. Limited to 10 seconds maximum when both outputs are shorted to Common at the same time. 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 expected operational life. All 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.
