RECOM provides a recommended PCB layout and thermal management guide in their application note AN-130, which can be found on their website. It's essential to follow these guidelines to ensure optimal performance, efficiency, and thermal reliability.
RECOM recommends following the guidelines outlined in their application note AN-120, which provides information on EMC considerations, filtering, and shielding. Additionally, the RB-0515S is designed to meet CISPR 22 Class B and EN 55022 Class B standards.
The maximum allowable capacitance on the output is not explicitly stated in the datasheet. However, RECOM recommends limiting the output capacitance to 10uF to 22uF to ensure stability and prevent oscillations.
While the RB-0515S is a high-quality DC-DC converter, it is not specifically designed for high-reliability or aerospace applications. RECOM offers other products, such as the RPA series, which are designed for these types of applications and meet relevant standards like MIL-STD-883 and ESCC 4000.
RECOM provides a derating curve for the RB-0515S in their datasheet, which shows the recommended output power reduction at high temperatures. The derating curve is based on the device's internal temperature, which can be estimated using the thermal resistance and power dissipation values provided in the datasheet.
