Next Generation 1W & 2W SIP Converters

TRACO Power TBA 1 and TBA 2 DC/DC Converters are designed to cover a broad range of low-power, cost-critical requirements. These 1W and 2W converters are available in industry-standard SIP-4 and SIP-7 packages and are designed as a cost-effective solution with enhanced capability. TRACO Power TBA 1 and TBA 2 DC/DC Converters include continuous short circuit protection and I/O isolations of 1500V_DC or 3000V_DC. The series has an operating temperature range of –40°C to +85°C without derating.
