1 a) F: a& I1 v. _; i- i% F& h$ BThe ZCC1001E is a high voltage, non-synchronous
step-down converter operates over a wide range
input voltage 9V to 100V. The ZCC1001E
# q* V; q* m/ Bintegrates a 120-V 400-mΩ high-side MOSFET.
% M" S, X  y4 ]$ _0 QThe ZCC1001E delivers 1A continuous load

operates with fixed frequency peak current control
with built-in compensation eliminates the need for
