3 WATT UNREGULATED WIDE INPUT RANGE DC/DC CONVERTER
PWR72
FEATURES
Low Price High Power Output: 3 Watts Wide Input Voltage Range: 5VDC To 22VDC Isolation Barrier 100% Tested Per UL544, VDE750, and CSA C22.2 Dielectric Withstand Isolation Barrier Leakage Current 100% Tested At 240VAC: 3A Max Low Isolation Barrier Capacitance: 10pF Single-Channel; Dual Output Six-Sided Shielding
DESCRIPTION
The PWR72 is a 3W, single-channel, dual-output DC/DC converter designed for low cost spot power conversion and ground elimination applications. It provides a plus and minus output voltage approximately equal to the input voltage magnitude. The PWR72 operates over a wide range of input voltages from 5VDC to 22VDC. Its unregulated outputs give the PWR72 high efficiency power conversion. Surface-mounted devices and manufacturing processes are used in the PWR72 to give the user a device which is more environmentally rugged than most DC/DC converters. The use of surface-mounted technologies also gives the PWR72 superior isolation voltage. A third advantage of using surfacemounted technologies is low manufacturing cost.
MECHANICAL
NOTES: All dimensions are in inches (millimeters). GRID: 0.100 inches (2.54 millimeters) Marked with: specific model ordered, date code, job code. MATERIAL: Units are encapsulated in a low thermal resistance molding compound which has excellent chemical resistance, wide operating temperature range, and good electrical properties under high humidity environments. Lead material is brass with a solder plated surface to allow ease of solderability.
