PRODUCTION DATA.
Measurements are done using typical application set up with connections shown in Figure 22 (snubber components included when VIN > 4 V). Graphs may not reflect the OTP default settings. Unless otherwise specified: VIN = 3.7 V, VOUT = 1 V, V(NRST) = 1.8 V, TA = 25°C, ƒSW = 4 MHz, L = 0.47 µH (TOKO DFE252012PD-R47M), COUT = 22 µF / phase, and CPOL = 22 µF / phase. Measurements are done using connections in the Typical Application.
