Application Field

TLV62568ADRLT is mostly used in automotive and consumer applications, such as 5V, 12V and 24V system rails, switching step-down converters, and LED backlight bias supplies. It is widely used in automotive and consumer applications due to its wide input voltage range, fast turn-on and good transient response characteristics. The device is also suitable for a variety of other DC-DC applications that require a high-efficiency, low noise buck-converter solution.

Working Principle

TLV62568ADRLT operates in a two stage process. First, it reads in an input voltage and regulates it by using its built-in MOSFETs to control the flow of current. Then it uses a buck converter to reduce the output voltage to the desired level. The device works by using the MOSFET switches in parallel to control the current flow through the buck converter. When the input voltage is higher than the desired output voltage, the MOSFETs are switched on and the voltage is reduced. On the other hand, when the input voltage is lower than the desired output voltage, the MOSFETs are turned off and the input voltage is taken as the output voltage.When the MOSFET switches are in their on-state, the input voltage is reduced by the buck converter and the output voltage is regulated. This process of rectifying and regulating the input voltage is efficient, as it minimizes power losses.

Conclusion

TLV62568ADRLT is a versatile switching regulator for automotive and consumer DC-DC applications. It is made from low RDS(ON) power MOSFET integrated regulators and a proportional or fixed output voltage. This switching regulator offers high efficiency, wide input voltage range, fast turn-on, transient response, integrated over temperature protection, integrated current limiter and over voltage protection. It is suitable for a variety of DC-DC applications that require a high-efficiency, low noise buck-converter solution.
