Evaluation board available. NX2114/2114A 300kHz & 600kHz SYNCHRONOUS PWM CONTROLLER PRELIMINARY DATA SHEET Pb Free Product DESCRIPTION FEATURES The NX2114 controller IC is a synchronous Buck con- n Synchronous Controller in 8 Pin Package troller IC designed for step down DC to DC converter n Bus voltage operation from 2V to 25V applications. Synchronous control operation replaces n Single 5V Supply Operation the traditional catch diode with an Nch MOSFET result- n Short protection with feedback UVLO ing in improved converter efficiency.Although the NX2114 n Internal 300kHz for 2114 and 600kHz for 2114A controller is optimized to convert single 5V bus voltages n Internal Digital Soft Start Function to supplies as low as 0.8V output voltage, however us- n Shut Down via pulling comp pin low ing a few external components it can also be used for n Pb-free and RoHS compliant other input supplies such as 12V input (See NX2113 data sheet for more optimized solution). The NX2114 operates at 300kHz while 2114A is set at 600kHz n operation which together with less than 50 nS of dead n band provides an efficient and cost effective solution. n Other features of the device are: Internal digital soft start; Vcc undervoltage lock out; Out- n put undervoltage protection with digital filter and shut- n down capability via the enable pin.
