LT1070HVCT#06PBF Application Field and Working Principle

LT1070HVCT#06PBF is a DC-DC switching regulator designed for a variety of applications requiring an adjustable output voltage ramp or an adjustable input current limit. It offers easily adjustable parameters, with an adjustable input voltage ramp, and a fixed output voltage of up to 14V. The LT1070HVCT#06PBF is designed to convert voltage from a regulated power supply to regulated output voltage with very low ripple and excellent line/load regulation. It is suitable for use in computing, communication, or any other application that requires a high efficiency, highly stable output voltage.

The LT1070HVCT#06PBF is a monolithic integrated circuit in a 5-pin dual in-line package (DIP). It features an on-chip charge pump that requires no external components, allowing the user to use the device in applications with limited space. The device provides an adjustable output voltage of up to 14V, and requires an external DC power supply, an output voltage ramp control potentiometer, and a PT-2 control voltage pin.

The working principle of LT1070HVCT#06PBF is based on a feedback loop that compares the actual output voltage, determined by the voltage divider, to the voltage set by the voltage ramp for a given time period. The difference between the actual output voltage and the programmed voltage controls the output switch, the switching controller, and the power switch, which controls the gates of the switching transistors. If the output voltage is higher than the programmed voltage, then the output switch is turned off, decreasing the output current. Likewise, if the output voltage is lower than the programmed voltage, then the output switch is turned on, increasing the output current. This feedback loop helps to maintain the output voltage within a very narrow range and assures an accurate output.

The LT1070HVCT#06PBF’s external components include a diode, a load resistor, an output capacitor, and an input capacitor. The diode passes current coming out of the output capacitor, allowing the pulses to reach the load. The load resistor limits the current that can flow into the load. The output capacitor stores energy before it is released to the load. The input capacitor conditions the input line by suppressing the high frequency components of the AC power line. All of these components play an important role in the LT1070HVCT #06PBF’s performance.

The LT1070HVCT#06PBF is an excellent choice for applications requiring high efficiency, good line/load regulation, precise voltage regulation, and low ripple. The device is easy to integrate and provides an adjustable output voltage of up to 14V. It is suitable for DC-DC switching regulator applications in a variety of industries such as computing, communication, and automotive. The device’s adjustable input voltage ramp and fixed output voltage provide great flexibility and performance.
