Typical Characteristics (continued)
Unless otherwise specified, the following conditions apply: V_IN = 12 V; C_IN = 2 x 10 μF + 1-μF X7R Ceramic; C_O = 220 μF
Specialty Polymer + 10-µF Ceramic; T_A = 25° C for waveforms. Efficiency and dissipation plots marked with * have cycle
skipping at light loads resulting in slightly higher Output ripple.
