DESCRIPTION

The NX2422 is a two-phase PWM controller with integrated FET driver designed for low voltage high current

application. The two phase synchronous buck converter offers ripple cancelation for both input and output.

FEATURES

Differential inductor DCR sensing eliminates the problem with layout parasitic

5V bias regulator available

Low Impedance On-board Drivers

Hiccup current limit and IOUT indication

Power Good for power sequencing

EN2_B pin allows the slave channel on and off while the master channel is working

Programmable frequency

Prebias start up

OVP without negative spike at output

Selectable between internal and external reference

Internal Schottky diode from PVCC to BST

Pb-free and RoHS compliant

APPLICATIONS
