When it may not be suitable

This module may not be appropriate for applications requiring output power exceeding 12W or those operating outside the specified 4.5-18V DC input range. It is also not intended for environments where the ambient temperature exceeds the thermal limits specified for natural convection without additional cooling measures.

Key specifications

• Power output: 12 W
• DC input voltage range: 4.5-18 V
• Output current: 1000 mA
• Isolation voltage: 1600 VDC
• Package type: SIP-8 metal package
• Dimensions: 9.6 mm x 12 mm x 22 mm

How to use

The converter is designed for direct mounting onto printed circuit boards. Ensure the input voltage is connected within the specified 4.5-18V range to the designated input pins. The output pins provide the regulated voltage to your load. Utilize the remote On/Off pin if external power management control is required. Proper PCB layout is essential to maintain the efficiency and thermal performance of the module.

What to consider before purchase

• Verify that your input power source falls within the 4.5-18V range.
• Check that your application load does not exceed the 12W power limit.
• Ensure the physical dimensions are compatible with your PCB space constraints.
• Confirm that the operating environment temperature is within the -40°C to +65°C range.

Usage recommendations

For optimal performance and to maintain the specified efficiency, ensure adequate airflow around the module and follow the recommended PCB layout guidelines provided by the manufacturer to manage heat dissipation effectively.
