2 s9 P9 T/ ^3 H) [Description
' e2 T8 ]% \: SZCC5160 is a step-down DC/DC regulator with an
# z0 j- `2 q9 Z$ Winternal switch, featuring SKIP control mode, which
combines low quiescent current with high switching
frequency to achieve high-efficiency regulation over a
% n0 \$ [, T1 l5 owide range of load currents. SKIP mode uses a short
"burst" cycle to switch the inductor current through
the internal power MOSFET, followed by a sleep
cycle in which the power switch is turned off and the
load current is provided by the output capacitor. At
% e7 s2 b- j4 D* f1 D1 klight loads, burst cycles are a small fraction of the
total cycle time, minimizing average supply current
