Overview: NX2422 TWO PHASE SYNCHRONOUS PWM CONTROLLER WITH INTEGRATED FET DRIVER, DIFFERENTIAL CURRENT SENSE & 5V BIAS REGULATOR PRELIMINARY DATA SHEET Pb Free Product The NX2422 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 5V bias regulator available 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 and IOUT indication NX2422 uses differential remote sensing using either curn Power Good for power sequencing rent sense resistor or inductor DCR sensing to achieve n EN2_B pin allows the slave channel on and off while accurate current matching between the two channels. the master channel is working Differential sensing eliminates the error caused by PCB n Programmable frequency board trace resistance that otherwise presents when usn Prebias start up ing a single ended voltage sensing. In addition the NX2422 offers high drive current capabil- n OVP without negative spike at output ity especially for keeping the synchronous MOSFET off n Selectable between internal and external reference during SW node transition, can provide regulated 5V to n Internal Schottky diode from PVCC to BST IC biasing and drivers via 5V bias regulator, allows the n Pb-free and RoHS pliant slave channel on and off via EN2_B pin while the main channel is working.
