If not otherwise specified, the following conditions apply: V
IN
= 12V; C
IN
= 2x10µF + 1µF X7R Ceramic; C
O
= 220µF Specialty Polymer + 10µF Ceramic; T
AMB
= 25°C for
waveforms. Efficiency and dissipation plots marked with * have cycle skipping at light loads resulting in slightly higher Output ripple.
