6.6 Typical Characteristics

Output inductor of L = 10 μH (part number SER1360-103L) was used for all 100-kHz efficiency measurements as well as those with the following conditions across all frequencies: (1) VIN = 3 V and VOUT = 2.5 V and (2) VIN = 3.3 V and VOUT = 2.5 V. For remaining 500-kHz and 1-MHz efficiency data, L = 2.7 μH (part number SER1360-272L).
