ontroller IC is a compact Buck controller IC with 16 lead MLPQ package designed for step down DC to DC converter in portable applications. It can be selected to operate in synchronous mode or non-synchronous mode to improve the efficiency at light n n n n n load.Constant on time control provides fast response, good line regulation and nearly constant frequency un- n der wide voltage input range. The NX2139 A controller is optimized to convert single supply up to 22V bus voltage to as low as 0.75V output voltage. Over current protection and FB UVLO followed by latch feature.
