NX2114A - NEXSEM

NX2114A 300kHz & 600kHz SYNCHRONOUS PWM CONTROLLER

The NX2114 controller IC is a synchronous Buck con- n troller IC designed for step down DC to DC converter n applications. Synchronous control operation replaces n the traditional catch diode with an Nch MOSFET result- n ing in improved converter efficiency. Although the NX2114 n controller is optimized to convert single 5V bus voltages n to supplies as low .

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.
