Description
The NX2210/2211 family of controller ICs are synchro- n
nous Buck controller IC designed for step down DC to DC converter applications.They are optimized to con- n vert bus voltages from 2V to 25V to outputs as low as n 0.8V voltage.Both devices offer an Enable pin that can n
be used to program the converter's start voltage using an external divider from bus voltage.The NX2211 oper- n ates at fixed 600kHz while 2210 has ability to program n switching frequency from 200kHz to 1MHz, making i
