Description

The NCV890430 is a fixed−frequency Synchronous Buckregulator intended for Automotive, battery−connectedapplications that operate with up to a 45 V input supply. Itis suitable for automotive systems requiring low noise andlow shutdown currents that also need to operate at low inputvoltage close to the output voltage. A reset pin (withadjustable delay) simplifies interfacing with amicrocontroller. This part also features an enable input thatcan either be connected to a low voltage (such as amicro−controller output) or high voltage (such as the batteryinput), and a synchronization input. The NCV890430 alsoprovides several protection features expected in automotive power supply systems such as current limit, short circuitprotection, and thermal shutdown. In addition, the highswitching frequency produces low output voltage rippleeven when using small inductor values and all−ceramicinput and output filter capacitors − forming a space−efficientswitching regulator solution.
