15-22 Watt Wide Input Range, Isolated DC-DC Converters / DCW Single Output 0$; 5() The DCW series offers a very broad input range for applications requiring high isolation. Output noise and ripple are low, and a high-attenuation filter reduces kickback spikes and reflected ripple from inverter switching. High frequency inverters provide high efficiency, close regulation, and rapid response. Switching elements are selected for the worst-case line, load, and temperature conditions. Since all thermal factors have been expertly engineered, internal temperature rise is minimal. Low thermal masses and thermal gradients allow minimum delay in reaching equilibrium after any change in operating conditions. • • • ,1 5() 0$; 7+',16(576 287 /2: 6((127( 5() 5() %277209,(: ( 6 $ & ; $ Wide: 2:1 Input Range High Input/Output Isolation No Heat Sink Required Direct PC Board Mounting Low Output Ripple 287 INPUT: 12, 24, 48 VDC OUTPUT: 5, 12, 15 VDC • • ,1 ( 6 $ & ( 6 $ & 8 $ : $ ',$ 0$; Dimensions in inches (mm) 0,1 0$; 0$; Specifications typical at +25°C MODELS DCW Input Voltage Input Current No Load Full Load Input Capacitance Input/Output Isolation Output Voltage Output Current at F.L.
