The NT3875 is a step down PWM converter with driving a output current up to 2A (NT3875A) a nd 1A (NT3875B) without a dditional tra nsistor.

It is de signed to allow f or operating a wide supply voltage ra nge from 8V to 40V .

The external shutdown function ca n be controlled by logic level to pull P/EN pin down, and then es into standby mode.

 VIN Operate with 8V ~ 40V Supply V oltage  V OUT Accura cy (Vref =1.2V) +1.0% Over Line Voltage  CC / CV Mode Control (Constant Current and Constant Voltage)  +/- 5% Current Limit Accuracy  Output Short Circuit Protection  Output Over Voltage Protection (~120%)  Over Temperature Prote ction  Internal Soft Start ~ 7ms  Fixed Frequency 120 KHz  UVLO Protection (min=6V, typ=7V, max=8V)  Duty Cycle Range (0~90%)  Single Pin to External Compensation and Shutdown Control  Integrated Powe.
