The NX2141 controller IC is a compact synchronous Buck controller IC designed for step down DC to DC converter applications with voltage feedforward functionality. Voltage feedforward provides fast response, good line regulation and nearly constant power stage gain under wide voltage input range. The NX2141 controller is optimized to convert single supply up to 24V bus voltage to as low as 0.8V output voltage. Internal UVLO keeps the regulator off until the supply voltage exceeds 7V where internal digital soft starts get initiated to ramp up output. The NX2141 employs fixed current limiting and FB UVLO followed by hiccup feature. Other features includes: 5V gate drive capability , Adaptive dead band control, available in 16 lead MLPQ and 10 lead MSOP package.
