Bivar recommends a PCB layout with a solid ground plane and thermal vias under the device to improve heat dissipation. A minimum of 2 oz copper thickness is recommended for optimal thermal performance.
To ensure reliable operation in high-vibration environments, Bivar recommends securing the device using a screw or adhesive, and using a PCB with a rigid construction to minimize flexure. Additionally, consider using a conformal coating to protect the device from environmental factors.
The maximum allowable voltage drop across the SM5730UWDC05 is 2.5V. Exceeding this voltage drop may result in reduced performance, increased power consumption, or even device failure.
While the SM5730UWDC05 is rated for operation up to 85°C, Bivar recommends derating the device's power dissipation by 50% when operating above 70°C to ensure reliable operation. Additionally, consider using a heat sink or thermal management system to maintain a safe operating temperature.
Bivar recommends a soldering profile with a peak temperature of 240°C ± 5°C, and a dwell time of 3-5 seconds. A soldering iron with a temperature range of 200-250°C is recommended for hand soldering.
