Typical Application
Description
: V; a3 r  ]4 l# G8 CThe ZCC1005 is a high voltage, non-synchronous
step-down converter operates over a wide range
input voltage

( `' s! t) f; a4 }integrates a 100-V 400-mΩ high-side MOSFET.
2 }* d& u% \! v8 AThe ZCC1005 delivers 1.5A continuous load
current with up to 95% efficiency. The ZCC1005

4 p( l$ f' j1 g- N* ?; W; ywith built-in compensation eliminates the need for
external components.
Cycle-by-cycle current limit in high-side MOSFET
protects the converter in an overload condition.
