LTM4650EY-1B#PBF

DC DC Converters

The LTM4650EY-1B#PBF is a type of DC DC converter. It is designed with a step-down or a buck converter topology and works with a wide range of input voltages. This type of converter offers exceptionally high efficiency and is suitable for a variety of applications.

Application Field

The LTM4650EY-1B#PBF is commonly used in automotive, aerospace, industrial, medical, and consumer applications. It is able to provide a regulated output voltage to applications that require a wide ratio of input to output voltage. For example, it can provide a regulated +5V output when supplied with an input voltage as low as 3V and as high as 20V.

Apart from the regulated +5V output, the LTM4650EY-1B#PBF can also provide a wider range of output voltage from 1.2V to 12V. This converter is suitable for powering microprocessors, digital signal processors, and other related application-specific integrated circuits.

Working Principle

The LTM4650EY-1B#PBF is a synchronous buck regulator which works on a synchronous rectification principle. The converter does not rely on an external Schottky diode for rectification but instead uses an internal FET as the synchronous rectifier. This means that the LTM4650EY-1B#PBF is able to achieve higher efficiency than conventional buck regulators.

The input voltage is stepped down using an inductor and a control circuit. The control circuit monitors the input voltage and adjusts the duty cycle of the inductor, which controls the amount of energy transferred from the primary side of the regulator to the secondary side and ultimately the output voltage. The output voltage is monitored and regulated by an internal error amplifier.

The LTM4650EY-1B#PBF also has multiple safety features to ensure reliable operation, such as over-voltage protection, under-voltage lockout, over-temperature protection, and cycle-by-cycle current limit. These features help to ensure reliable operation and protection against transient events.

Conclusion

The LTM4650EY-1B#PBF is a highly efficient DC DC converter suitable for a wide range of applications. It is able to provide a regulated output voltage with high efficiency, and it has multiple safety features to ensure reliable operation. This type of converter is commonly used in automotive, aerospace, industrial, medical, and consumer applications.
