controller IC is a synchronous Buck con- troller IC designed for step down DC to DC converter applications. Synchronous control operation replaces the traditional catch Diode
with an Nch MOSFET result- ing in improved converter efficiency . Although the NX2114
controller is optimized to convert single 5V bus voltages to supplies as low as 0.8V output voltage, however us- ing a few external components it can also be used for 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 operation which together with less than 50 nS of dead band provides an efficient and cost effective solution. Other features of the device are: Internal digital soft start; Vcc undervoltage lock out; Out- put undervoltage protection with digital Filter
and shut- down capability via the enable pin.
