NX2415

NEXSEM Evaluation board available. NX2415 TWO PHASE SYNCHRONOUS PWM CONTROLLER WITH INTEGRATED FET DRIVER AND DIFFERENTIAL CURRENT SENSE PRELIMINARY DATA SHEET Pb Free Product The NX2415 is a two-phase PWM controller with inte- n Differential inductor DCR sensing eliminates the problem with layout parasitic grated FET driver designed for low voltage high current n External programmable voltage droop application. The two phase synchronous buck converter n Low Impedance On-board Drivers offers ripple cancelation for both input and output. The n Hiccup current limit NX2415 uses differential remote sensing using either current sense resistor or inductor DCR sensing to achieve n Power Good for power sequencing accurate current matching between the two channels. n Enable Signal allows external shutdown as well as programming the BUS voltage start up threshold Differential sensing eliminates the error caused by PCB n Programmable frequency board trace resistance that is otherwise is present when n Prebias start up using a single ended voltage sensing. In addition the n Over voltage protection without negative spike at NX2415 offers high drive current capability especially for output keeping the synchronous MOSFET off during SW node transition, accurate programmable droop allowing to re- n Pb-free and RoHS compliant duce number of output capacitors, accurate enable circuit provides programmable start up point for Bus volt- n Graphic card High Current Vcore Supply age, PGOOD outpu...
