The VI Chip® bus converter is a high efficiency (>95%), narrow input range Sine Amplitude Converter (SAC) operating from a 38 to 55 Vdc primary bus to deliver an isolated 6.34 V to 9.16 V secondary. It may be used to power non-isolated POL converters or as an independent 6.34 – 9.16 V source. Due to the fast response time and low noise of the bus converter, the need for limited life aluminum electrolytic or tantalum capacitors at the load is reduced or eliminated. The bus converter achieves a power density of 813 W/in³ in a VI Chip package compatible with standard pick-and-place and surface mount assembly process. The VI Chip package provides flexible thermal management through its low junction-to-board and junction-to-case thermal resistance. Owing to its high conversion efficiency and safe operating temperature range, the bus converter does not require a discrete heat sink in typical applications. Low junction-to-case and junction-to-lead thermal impedances assure low junction temperatures and long life in the harshest environments. MTBF is 3.5 million hours.
