Typical Application
; q& U. Z9 T$ TDescription
The ZCC1001E is a high voltage, non-synchronous
5 s' ^: D% s. p+ ~/ fstep-down converter operates over a wide range
input voltage 9V to 100V. The ZCC1001E
integrates a 120-V 400-mΩ high-side MOSFET.
The ZCC1001E delivers 1A continuous load
current with up to 95% efficiency. The ZCC1001E
6 {. ?7 u7 X8 Koperates with fixed frequency peak current control
with built-in compensation eliminates the need for
