Description
8 X2 r/ N- c- T$ cThe ZCC1008B is a high voltage, synchronous
step-down controller operates over a wide range input
voltage 9V to 100V. The ZCC1008B delivers 10A
continuous load current with up to 96% efficiency.
. m0 d2 H2 Y4 PThe ZCC1008B operates with fixed frequency peak
' S7 z8 T2 B4 Z0 U+ N+ G3 Ecurrent control with 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. Hiccup mode protection is triggered
$ t3 P1 }) e$ M2 [% R/ ]/ vif the over-current condition has persisted for longer
than the present time. The ZCC1008B exhibits
protection feature that protect the load from faults like
9 K' O# F' w* Vunder-voltage,over-current and over-temperature.
