8.2.3 Application Curves
Measurements are done using typical application set up with connections shown in Typical Applications. Graphs
may not reflect the OTP default settings. Unless otherwise specified: V(VIN_Bx) = V(VIN_LDOx) = V(VANA) = 3.7 V,
VOUT_Bx = 1 V, VOUT_LDOx = 1 V, TA = 25°C, L = 0.47 µH (TOKO DFE252012PD-R47M), COUT_BUCK = 22 µF /
phase, and CPOL_BUCK = 22 µF, COUT_LDO = 1 µF.
VOUT = 1.8 V

Mode (Single-Phase Output)
VOUT = 1.8 V
Figure 72. Buck Efficiency in PFM/PWM and Forced PWM
Mode (Dual-Phase Output)
VIN = 3.3 V
Figure 73. Buck Efficiency in Forced PWM Mode (Single-
Phase Output)
VIN = 3.3 V
