Description:Display Modules - LED Character and Numeric Orange-Red 7-Segment 1 Character Common Cathode 2V 20mA 1.090" H x 0.783" W x 0.330" D (27.69mm x 19.90mm x 8.38mm) 18-DIP (0.600", 15.24mm), 13 Leads
The recommended PCB layout for optimal thermal performance involves placing the device on a thermal pad with a minimum size of 10mm x 10mm, and ensuring that the thermal pad is connected to a large copper area on the PCB to dissipate heat efficiently.
To ensure reliable operation in high-temperature environments, it is recommended to derate the device's power dissipation according to the temperature derating curve provided in the datasheet, and to ensure good airflow around the device to prevent thermal buildup.
The recommended soldering profile for the LTS-3403LE involves a peak temperature of 260°C, with a dwell time of 10-30 seconds above 220°C. It is also recommended to use a solder with a melting point of 217°C or higher.
To troubleshoot issues with the device's output voltage regulation, check the input voltage, output load, and feedback resistors for correct values and connections. Also, ensure that the device is properly decoupled with input and output capacitors, and that the PCB layout is not causing any noise or oscillation issues.
The recommended input capacitor type for the LTS-3403LE is a low-ESR ceramic capacitor with a value of 10uF to 22uF. The capacitor should be placed as close to the device's input pins as possible to minimize noise and ripple.
