LT1072CN8#PBF Application Field and Working Principle

The LT1072CN8#PBF is a low voltage, monolithic synchronous switching regulator that has been designed for efficiency, stability, and accuracy. It is capable of providing voltages as low as 0.225V and as high as 19V. The LT1072CN8#PBF is typically used in power supply applications such as distributed power systems, high-performance computing, and telecom power systems. In addition, it is suitable for general purpose voltage regulation, such as portable battery powered applications and automotive power systems.

The LT1072CN8#PBF operates on a switching cycle of several thousand hertz. It uses an external P-channel MOSFET in order to regulate the current going into its power output. The external MOSFET provides protection against output over-voltage and overload conditions and has the ability to adjust its frequency and duty cycle in order to maintain its desired output voltage. The LT1072CN8#PBF also features a maximum duty cycle of 99%, allowing it to provide a wide range of output voltages and currents. The operating frequency of the LT1072CN8#PBF can be adjusted by either the internal oscillator or an external clock signal.

In addition to the external MOSFET, the LT1072CN8#PBF includes several internal protection features. These include an over-current-limiting circuit, an over-temperature circuit, a high current gate drive circuit, an over-voltage circuit, and a fast slew-rate limiting circuit. The LT1072CN8#PBF also includes a unique circuit which provides a soft-start for the regulator. This soft-start circuit prevents the output voltage from climbing too quickly and helps to reduce the input current. The LT1072CN8#PBF is designed to operate efficiently at high temperatures and to provide superior transient response when compared to linear regulators.

The LT1072CN8#PBF is an ideal solution for low-voltage, low-power applications. Its low operating voltages, high maximum duty cycle, and internal protection features make it the ideal choice for a wide range of power supplies and systems. The LT1072CN8#PBF is available in 8-lead, PBF packages and is fully RoHS compliant.
