This article will discuss the application field and working principle of the LTC1966HMS8#PBF.

Application Field

The LTC1966HMS8#PBF can be used in a variety of applications, such as:

• AC/DC conversion
• DC/DC conversion
• Switching power supplies
• Telecommunications
• Networking
• Computer peripherals
• Industrial and consumer applications

Due to its exceptional performance over time and wide range of applications, the LTC1966HMS8#PBF can be used in both commercial and industrial applications, including at the power distribution level.

Working Principle

The LTC1966HMS8#PBF is a peak current mode switched controller. Its output voltage is determined by an internal voltage reference and external components, allowing it to provide a wide output voltage range and high efficiency. The constant frequency current mode architecture provides fast line and load transient response, excellent line and load regulation and low output ripple voltage. It also offers programmable soft start and output over-current protection.

The LTC1966HMS8#PBF draws current through an internal current sense amplifier in order to detect the peak of the inductor current during each cycle of the switching operation. When the peak current value is reached, the LTC1966HMS8#PBF turns off the high-side switch. The power switch is then turned off and the output voltage is regulated. The cycle then repeats and the peak current is adjusted in order to maintain accurate output regulation.

The LTC1966HMS8#PBF features an adjustable switching frequency which can range from 50kHz to 500kHz depending on design requirements. The LTC1966HMS8#PBF can also operate in Burst Mode to reduce noise and improve system efficiency when the output current is below a certain threshold.

Conclusion

The LTC1966HMS8#PBF is a precision, current mode, constant frequency peak current mode controller that is suitable for a wide variety of applications ranging from AC/DC and DC/DC converters to telecommunications, networking, computer peripherals and industrial and consumer applications. It offers high efficiency, superior line and load regulation, programmable soft start and output over-current protection, adjustable switching frequency and Burst Mode operation. It is an ideal solution for applications requiring high power density and excellent performance.
