The ZCC1001E is a high voltage, non-synchronous
' r" E7 {  x# [/ }step-down converter operates over a wide range
input voltage 9V to 100V. The ZCC1001E
  n: i6 z$ H, M8 |5 O0 }, rintegrates a 120-V 400-mΩ high-side MOSFET.
The ZCC1001E delivers 1A continuous load
current with up to 95% efficiency. The ZCC1001E
