The NJW4128 is a buck converter with 40V/2.5A MOSFET. It corresponds to high oscillating frequency, and Low ESR Output Capacitor (MLCC) within wide input range from 4.5V to 40V. Therefore, the NJW4128 can realize downsizing of applications with a few external parts so that adopts current mode control. Also, it has a soft start function, external clock synchr.
Current Mode Control External Clock Synchronization Wide Operating Voltage Range 4.5V to 40V Switching Current 3.6A min. PWM Control Built-in Compensation Circuit Correspond to Ceramic Capacitor (MLCC) Oscillating Frequency 450kHz typ. (A ver.) 300kHz typ. (B ver.) Soft Start Function 4ms typ. UVLO (Under Voltage Lockout) Over Current Protection (Hiccup type) Thermal Shutdown Protection Power Good Function Standby Function Package Outline NJW4128GM1 : HSOP8 http://www.DataSheet4U.net/ PRODUCT CLASSFICATION Part Number NJW4128GM1-A NJW4128GM1-B Version A B Oscillation Frequency 450kHz typ. 300.
