The bus converter PC to -In -0.3 to 7.0 Vdc may be used to power non-isolated POL converters or as +Out to -Out -0.5 to 16 Vdc an independent 6.34 9.16 V source. Due to the fast response time and low noise of the bus converter, the Isolation voltage 2,250 Vdc Input to output need for limited life aluminum electrolytic or tantalum Output current 39 A Continuous capacitors at the load is reducedor eliminated Peak output current 45.0 A For 1 ms resulting in savings of board area, materials and total Output power 240 W Continuous system cost. Peak output power 360 W For 1 ms 3 The bus converter achieves a power density of 813 W /in 225 C MSL 5 a in a VI Chip package compatible with standard pick-and- Case temperature during reflow 245 C MSL 6, TOB = 4 hrs place and surface mount assembly process. The VI Chip package provides flexible thermal management -40 to 125 C T-Grade b Operating junction temperature through its low junction-to-board and junction-to-case -55 to 125 C M-Grade thermal resistance. Owing to its high conversion -40 to 125 C T-Grade Storage temperature efficiency and safe operating temperature range, the bus -65 to 125 C M-Grade converter does not require a discrete heat sink in typical Notes: applications. Low junction-to-case and junction-to-lead a 245C reflow capability applies to product with manufacturing date code 1001 and greater. thermal impedances assure low junction temperatures b The referenced junction is defined as the semiconductor having the highest temperature. and long life in the harshest environments. This temperature is monitored by a shutdown comparator.
