TYPICAL PERFORMANCE CHARACTERISTICS (continued)
Unless otherwise specified, the following conditions apply: V
IN
= 12V; Cin = 2 x 10μF + 1μF X7R Ceramic; C
O
= 220μF
Specialty Polymer + 10 uF Ceramic; TAmbient = 25° C for waveforms. Efficiency and dissipation plots marked with * have
cycle skipping at light loads resulting is slightly higher Output ripple – See Design Steps for the LMZ22003 Application
section.
