Description
The ZCC1005 is a high voltage, non-synchronous
step-down converter operates over a wide range

6 Y1 m1 O; F& ointegrates a 100-V 400-mΩ high-side MOSFET.
4 P: w: r7 W% oThe ZCC1005 delivers 1.5A continuous load
current with up to 95% efficiency. The ZCC1005
operates with fixed frequency peak current control
