Description
The NJW4750 is quad channel combination regulator including one wide input range buck converter and three secondary synchronous buck converter / LDO. Ch.3 can be selectable to the synchronous buck converter mode or LDO mode. Therefore, the NJW4750 expands the choices when building power supply block suitable for various applications. The NJW4750 is operated anti-phase operation between Ch.1 and Ch.2 / 3 in order to reduce EMI noise. Every regulator has individual enable pin and powergood pin. Therefore, flexible power-on sequence configuration is available. The NJW4750 has two types of over-current protection according to application demand. Furthermore, it adopts a new overcurrent detection method which is more safety and contributes to miniaturization of the inductor. Small package: 3.4mm × 2.6mm QFN is adopted suitable for small application such as camera module.
