Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps: TSC102IDT Application Field and Working Principle

The TSC102IDT is an integrated circuit containing technology for a single-ended, high-voltage charge pump, useful in a variety of applications. It is designed for a negative voltage output stage and features: adjustable output voltage from 0.2V to 1000V; low operating voltage from 0.80V to 25V; low operating temperature from -20°C to 110°C; 0.05% accuracy in output regulation; and a switch-off leakage current of less than 0.2mA.

TSC102IDT is a charge pump integrated circuit that can be used in a variety of applications that require the use of a higher voltage than the input voltage. It is designed to provide an output voltage of up to 1000V and has a low operating voltage of 0.80V to 25V. It has a 0.05% accuracy in output regulation, adjustable output voltage, and a switch-off leakage current of less than 0.2mA. This integrated circuit also offers excellent thermal stability and improved efficiency over traditional linear amplifiers.

The TSC102IDT is also ideal for use in systems that are sensitive to voltage, such as those using high-voltage MOSFETs, and for applications such as video circuit protection and display driver circuits. It is also used for the production of high AC, DC, and pulse voltages for various test and measurement tools.

The working principle of the TSC102IDT is based on the input voltage being converted into a higher output voltage by a charge pump circuit. A charge pump is an integrated circuit designed to convert low-voltage alternating current (AC) signals into higher voltage direct current (DC) signals, as well as providing isolation between input and output signals. It works by drawing energy from the input AC voltage and storing it in a capacitor or inductor and then transferring it to the output voltage.

The TSC102IDT includes a low-side driver, P-channel MOSFET, high-side driver, N-channel MOSFET and two outputs. The input voltage is divided in half; the negative or ground is connected to the input terminal of the low-side driver, while the positive is connected to the output terminal of the high-side driver. As the input voltage increases, a PWM signal is generated by the low-side driver, which turns on the N-channel MOSFET of the high-side driver, resulting in the voltage at the output terminal of the high-side driver being equal to the input voltage multiplied by a factor of two.

The TSC102IDT also features a Dynamic Output Voltage Limiting (DOL) mode, which helps to regulate the output voltage and protect from accidental voltage spikes. The DOL mode is activated when the output voltage reaches a preset limit, and is designed to reduce the output voltage to its original value. This feature is particularly useful in applications where the output voltage may be subject to transient spikes due to external noise or sudden changes in load conditions.

The TSC102IDT is an efficient and reliable integrated circuit that can be used in a variety of applications requiring the use of a higher voltage than the input voltage. It is designed for a negative voltage output stage and features adjustable output voltage from 0.2 V to 1000V, low operating voltage from 0.80V to 25V, 0.05% accuracy in output regulation, and a switch-off leakage current of less than 0.2mA. It provides excellent thermal stability and improved efficiency over traditional linear amplifiers.
