Description
& L: T: j4 ?% r, O& aThe ZCC1005 is a high voltage, non-synchronous
step-down converter operates over a wide range

5 r! s* T- W! ~" QThe ZCC1005 delivers 1.5A continuous load
current with up to 95% efficiency. The ZCC1005
operates with fixed frequency peak current control
with built-in compensation eliminates the need for
external components.
Cycle-by-cycle current limit in high-side MOSFET

$ `  O3 J- v1 {: z; y$ JHiccup mode protection is triggered if the
+ \( Y/ `3 i  E$ pover-current condition has persisted for longer than
the present time.
The ZCC1005 exhibits protection features that
protect the load from faults like under-voltage,
over-current and over-temperature.
The ZCC1005 is available in an ESOP-8 package.
