The maximum operating temperature range for the JCH1024S05 is -40°C to +85°C, with a derating of 2.5% per °C above 60°C.
The JCH1024S05 meets various safety certifications, including UL60950-1, EN60950-1, and IEC60950-1. Ensure you follow the recommended layout and component selection guidelines to maintain these certifications in your application.
The recommended input capacitor value is 10uF to 22uF, with a voltage rating of 25V or higher. A low-ESR capacitor, such as an X7R or X5R ceramic capacitor, is recommended to minimize input ripple and ensure stable operation.
Use the power dissipation formula provided in the datasheet, taking into account the input voltage, output voltage, and output current. A heat sink with a thermal resistance of 10°C/W or lower is recommended to maintain a safe operating temperature.
Follow the recommended PCB layout and component placement guidelines in the datasheet, ensuring that the input and output capacitors are placed close to the device, and the heat sink is properly connected to the device.
