This data is considered typical data for the converter. EFFICIENCY POWER DISSIPATION vs vs LOAD CURRENT LOAD CURRENT CROSS REGULATION Figure 13. Figure 11. (1) Figure 12. (1) CROSS REGULATION SAFE OPERATING AREA Figure 14. Figure 15. (1) (2) (1) Under a balanced load, current flowing out of VO1 is equal to that flowing into VO2. (2) 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. Copyright © 2004–2007, Texas Instruments Incorporated 9 |
