The KA3846 control IC provides all of the necessary features

to implement fixed frequency, current mode control

schemes while maintaining a minimum external parts count.

The superior performance of this technique can be measured

in improved line regulation, enhanced load response characteristics,

and a simpler, easier-to-design control loop.

Topological advantages include inherent pulse-by-pulse current

limiting capability, automatic symmetry correction for

push-pull converters, and the ability to parallel “power

module,, while maintaining equal current sharing. Protection

circuitry includes built-in-under-voltage lockout and programmable

current limit in addition to soft-start capability.

A shutdown function is also available which can initiate

either a complete shutdown with automatic restart or latch

the supply off. Other features include fully latched operation,

double pulse suppression, deadtime adjust capability, and

±2% trimmed bandgap reference. The KA3846 features low

outputs in the OFF state.

    The service is excellent, fast shipping and great communication, i tried to get this parts here in mexico and are hard to find, even in the downtown. I am trying to repair a car amplifier and only need two other pieces. I will contact you first to get any components in the future. Thanks a lot.
