7.10 Typical Characteristics
Typical characteristics taken with the CDFP package option. Efficiency data was collected using the TPS7H4001EVM-CVAL with 2 inductors in parallel. For 100-kHz data, each inductor was L = 10 µH, part number = SER1390-103ML. For 500-kHz and 1000-kHz data, each inductor was L = 1.8 µH, part number = SER1360-182KL.
