Working Principle of LM2674M-5.0

The LM2674M-5.0 is a high-performance, low-power, low-dropout, low-voltage, synchronous step-down DC/DC converter based on vector modulation technology. The device utilizes a synchronous rectifier and current-mode control to achieve high efficiency and fast transient response. The device automatically shifts between active and sleep modes, thus reducing quiescent current in dip state. The device employs a FlexFET PowerLite FET which reduces both starting RDS(ON) and dropout. The device also includes built-in current limit and thermal shutdown protection.

The device has an adjustable 4-pin voltage control interface that can be used to adjust both output voltage and current-limit thresholds. The voltage control signal is provided by a resistor divider that allows the output to be precisely controlled and adjusted. The quiescent current can be reduced by entering into a standby state. The device also includes a hiccup reset output that monitors the DC-IN supply for a major fault. When a fault occurs, the device immediately shuts down the output and resets itself.

In addition, the device provides superior thermal performance and is available in a WSON-6 package. The product offers low component count, low external component cost, high operating temperature and high efficiency making it ideal for distributed power applications.

The LM2674M-5.0 is an excellent voltage regulator that can be used in a variety of applications. It provides superior performance, features, and user safety features that make it suitable for use in mobile and distributed power applications. With its low component count, low external component cost, high operating temperature and high efficiency, it is a great choice for distributed power applications.
