NX2423
NX2423 - Brand New Microchip Technology IC Chips
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
DESCRIPTION
The NX2423 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. The NX2423 uses
differential remote sensing using either current sense resistor or inductor
DCR sensing to achieve accurate current matching between the two channels.
Differential sensing eliminates the error caused by PCB board trace resistance
that otherwise presents when us ing a single ended voltage sensing.
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
Graphic card High Current Vcore Supply
High Current on board DC to DC converter applications
