ELECTRICAL CHARACTERISTICS
values are referenced to T
NOTES:
8. Efficiency is defined by 100 * (Pout / Pin), Vin = 3.1 to 4.2 V, L = VLF3010AT-4R7MR70 (DCR = 280 mW max, Isat = 700 mA), Load = 15
9. Guaranteed by design and characterized.
10. Typical application circuit and components depicted Figure 1.
11. Tested at 25°C and guaranteed from -40°C to +85°C by characterization.
12. Line drop and rise between 3.4 to 2.9 V in 50 ms at I
13. Ripple = 0.2 V p-p at 25°C, Cout = 4.7 mF, I
14. I
15. Load step 10 to 90 mA and 90 to 10 mA, rising and falling edge in 10 ms, Cout = 4.7 mF, V
