Application field

The NB633EL-LF-P is suitable for a wide variety of applications, including but not limited to automotive, industrial, consumer, and medical. In automotive applications, it can be used as an on-board or engine control unit. In industrial applications, it can be used as the DC supply for drives, solid-state relays, actuators, or power control applications. In consumer applications, it can be used to power high-performance portable devices or to improve overall system efficiency. In medical applications, it can be used to power medical equipment such as patient monitors and diagnostic instruments.

Working Principle

The NB633EL-LF-P is a synchronous rectified buck converter. It takes the input voltage and converts it to the required output voltage. It does this by controlling a set of switches, which either connects the input voltage to the output or disconnects it. When the switches are open, the output voltage is equal to the input voltage. When the switches are closed, the output voltage is equal to the output voltage set by the regulation loop.The NB633EL-LF-P has an integrated high-accuracy voltage reference, finely tuned to control the switching frequency. It features a fast transient response and low jitter, which makes it ideal for communications systems. The integrated frequency compensation simplifies converter design and increases system reliability. It also features a low-quiescent current mode, which significantly reduces power consumption.
