Description
The NX2601 controller IC is a triple controller with a dual n channel synchronous Buck controller IC and an LDO n controller designed for multiple converters such as PCIe graphic card applications .The two synchronous PWM n controllers are 180 degree out of phase which reduces n the input ripple current, allowing to reduce the # of input n capacitors.Another main feature of the part is that it can n operate from single 12V supply while maintaining a regu- n lated 5V supply for the biasing and the internal drivers. Other features of NX2601 are; programmable frequency n from 200kHz to 1MHz, independent digital soft start and enable pins for each controller which allows for different n power sequencing, Adaptive driver provides optimized n efficiency while maintain sufficient deadband, Vcc n undervoltage lock out and current limiting using an Rds- on of the external MOSFET with HICCUP feature. n.
