NX2601 - NEXSEM

NX2601 DUAL SYNCHRONOUS PWM CONTROLLER

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.Anoth.

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 FEATURES Two channel PWM with out of phase operation Individual digital soft start for two PWM output and LDO controller Bus voltage operation from 2V to 25V Hiccup Current limit by sensing Rdson of MOSFET Adjustable frequen.
