NCP3121MNTXG

The NCP3121MNTXG is one member of the NCP3121 family which designed as one kind of dual 3.0A,step-down DC/DC switching regulator.It is capable of producing an output voltage as low as 0.8 V. The NCP3121MNTXG provides dual 3.0 A switching regulators with an adjustable 200 kHz-750 kHz switching frequency and also incorporates an auto-tracking and sequencing feature.

Features of the NCP3121MNTXG are:(1)200-750 kHz operation;(2)input voltage range from 4.5 V to 13.2 V;(3)stable with low ESR ceramic output capacitor;(4)0.8±1.5% FB reference voltage;(5)external soft-start;(6)out of phase operation of OUT1 & OUT2;(7)auto-tracking and sequencing;(8)enable/disable capability;(9)hiccup overload protection;(10)low shutdown power (Iq<100uA).And it can be used in set-top boxes, portable applications, networking and telecommunications.

The absolute maximum ratings of the NCP3121MNTXG can be summarized as:(1)power supply voltage input:-0.3 to 15 V;(2)signal supply voltage input:-0.3 to 15 V;(3)SW pin voltage:-0.7 to Vvin V;(4)EN pin voltage input:-0.3 to 8.0 V;(5)SEQ pin voltage output:-0.3 to 8.0 V;(6)PG pin voltage:-0.3 to 5.5 V;(7)all other pins:-0.3 to 5.5 °V;(8)thermal resistance,junction-to-ambient:50°C/W;(9)storage temperature range:-55 to +150°C;(10)junction operating temper-ature:-40 to +150°C.If you want to know more information such as the electrical characteristics about the NCP3121MNTXG,please download the datasheet in www.seekic.com or www.chinaicmart.com .
