Description
, c- X, a- Q/ I9 e* c5 xZCC5160 is a step-down DC/DC regulator with an
internal switch, featuring SKIP control mode, which
combines low quiescent current with high switching
/ P9 R( h6 Z, @8 yfrequency to achieve high-efficiency regulation over a
& d; |. t! e  Q2 Y/ A: iwide range of load currents. SKIP mode uses a short
"burst" cycle to switch the inductor current through

load current is provided by the output capacitor. At
light loads, burst cycles are a small fraction of the

ZCC5160 has a wide input voltage range of 4V-60V,

use in the 48V automotive power bus range.
ZCC5160 features low-value 100mΩ high-side and

output current capability with excellent load and line
transient response.
