Figure 14. CROSS REGULATION ∆Vo x vs Ioy SAFE OPERATING AREA Iox = 1 A and VI = 48 V VI = 48 V Figure 15. Figure 16. (1) A. Characteristic data has been developed from actual products tested at 25 °C. This data is considered typical data for the converter. (2) B. Load current is increased proportionally from both outputs, up to the indicated maximum value of each respective output. (3) C. SOA curves represent the conditions at which internal components are at or below the manufacturer's maximum operating temperatures. Derating limits apply to modules soldered directly to a 4 in. × 4 in. double-sided PCB with 1 oz. copper. 10 Submit Documentation Feedback PTB48500A and PTB48502A are Not Recommended for New Designs |
