Board specifications are as follows:
• Input Range: 20 V to 100 V
• Primary Output Voltage: 10 V
• Secondary (Isolated) Output Voltage: 9.5 V
• Maximum Load Current (Primary + Secondary): 300 mA
• Maximum Power Output: 3 W
• Nominal Switching Frequency: 750 kHz
• Efficiency (FIN = 48 V, IOUT2 = 300 mA): 76 percent
• Board size: 2 inch x 2 inch
