LT1070CT#PBF is a DC-to-DC switching regulator. It is designed to provide accurate voltage regulation and low power consumption, making it suitable for a variety of applications such as cell phones and power management in General-Purpose Data Acquisition Systems.The LT1070CT#PBF can work either as a positive voltage or a negative voltage regulator. It contains an oscillator that has a wide operating range and is capable of running at frequencies up to 150 kHz. It is also equipped with a built-in power-ON reset, lowering the need for external circuitry. The device can be configured to provide either a fixed output voltage or an adjustable output voltage.The device utilizes a synchronous rectifier circuit, which provides a high level of efficiency due to low power dissipation when compared to a conventional linear regulator. The switch is driven by an external drive voltage and contains a built-in error amplifier which senses the output voltage and is used to provide regulation. The device also contains two feedback elements; a resistor connected between the output and the error amplifier which sets the output voltage, and a capacitor connected between the error amplifier and ground which provides current limiting and prevents overcurrent conditions. A typical application circuit is as follows: a resistor and/or inductor are connected to the RT/CT and LN/H pins, which form the synchronous rectifier circuit that holds the voltage across the load and provides fast response over various load conditions. The error amplifier, formed by resistors coupled to the feedback and ground pins, sense the output voltage and regulate the output. The oscillator is realized by an N-type MOSFET connected to the RT and CT pins, with the OSC pin providing the control voltage for frequency control. The LT1070CT#PBF is suitable for applications where a low input voltage, high accuracy and low power consumption are needed. Its wide operating range allows it to be used in a variety of environments and applications, while its built-in features reduce the need for external circuitry, making it a cost-effective solution.
