Description
The ZCC1001E is a high voltage, non-synchronous
step-down converter operates over a wide range
* }  m: P( Q4 y9 R: p7 L: _' a! h# cinput voltage 9V to 100V. The ZCC1001E
integrates a 120-V 400-mΩ high-side MOSFET.
The ZCC1001E delivers 1A continuous load
5 \# D* x+ I' ^( ]- B9 `8 I! w: ccurrent with up to 95% efficiency. The ZCC1001E

1 K2 t$ M1 r' v- s% D' R$ a; GCycle-by-cycle current limit in high-side MOSFET
protects the converter in an overload condition.
Hiccup mode protection is triggered if the over

The ZCC1001E exhibits protection features that

over-current and over-temperature.
The ZCC1001E is available in an ESOP-8 package.
