NX2305 SINGLE SUPPLY 12V SYNCHRONOUS PWM CONTROLLER WITH NMOS LDO CONTROLLER DESCRIPTION The NX2305 controller IC is a combination synchronous n Buck and LDO controller IC designed to convert single n 12V supply to low cost dual on board supply applica- n tions. The synchronous controller is used for high cur- n rent high efficiency step down DC to DC converter appli- n cations while the LDO controller in conjunction with an n external low cost N ch MOSFET can be used as a very n low drop out regulator in applications such converting n 3.3V to 2.5V output. Internal UVLO keeps both regula- tors off until the supply voltage exceeds 9V where inde- pendent internal digital soft starts get initiated to ramp n up both outputs.
