Microsemi NX2154A

The NX2154/2154A controller IC is a synchronous Buck n Bus voltage operation from 2V to 40V controller IC designed for step down DC to DC con- n Fixed 300kHz voltage mode controller verter applications. It is optimized to convert bus volt- n Internal Digital Soft Start Function ages from 2V to 40V to outputs as low as 0.8V voltage. The n Less than 50 nS adaptive deadband NX2154/2154A employs fixed loss-less current limiting n Current limit triggers hiccup by sensing Rdson of by sensing the Rdson of synchronous MOSFET followed Synchronous MOSFET by hiccup feature.NX2154A has higher current limit n No negative spike at Vout during startup and threshold than NX2154.
