Description
ZCC5160 is a step-down DC/DC regulator with an
( I  \* U: R4 r, ]; {internal switch, featuring SKIP control mode, which
combines low quiescent current with high switching
frequency to achieve high-efficiency regulation over a
wide range of load currents. SKIP mode uses a short
"burst" cycle to switch the inductor current through
( s" g1 ?- t/ g0 Qthe internal power MOSFET, followed by a sleep
cycle in which the power switch is turned off and the
( T0 f) U: r% l9 Y; eload current is provided by the output capacitor. At
% x3 y% l; b5 z2 D9 s+ z$ Qlight loads, burst cycles are a small fraction of the
total cycle time, minimizing average supply current
and greatly improving efficiency at light loads.
5 q5 K3 V% L* h/ [ZCC5160 has a wide input voltage range of 4V-60V,
thus minimizing the need for external surge
" S6 O" b7 N! r+ Usuppression components. Making it the best choice
for wide input power range industrial and high cell
count battery pack applications. ZCC5160 is ideal for

Additional features include: soft-start, thermal
shutdown, UVLO undervoltage lockout, gate driver
+ i$ L; p5 u+ Vundervoltage lockout, maximum duty cycle limit timer,
and current limit shutdown timer. It also integrates
output short-circuit protection, providing HICCUP
mode when the FB voltage is low to avoid
overheating during short-circuit.
