The NX2139A controller 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 .
includes: 5V gate drive capa- bility, power good indicator, over voltage protection, n internal Boost schottky diode and adaptive dead band n control. n n Pb Free Product FEATURES Internal Boost Schottky Diode Ultrasonic mode operation available Bus voltage operation from 4.5V to 22V Less than 1uA shutdown current with Enable low Excellent dynamic response with constant on time control Selectable between Synchronous CCM mode and diode emulation mode to improve efficiency at light load Programmable switching frequency Current limit and FB UVLO with latch off Over voltage protection with l.
