L6984TR Integrated Circuits (ICs)

The L6984TR is a switch mode voltage regulator (SMPS) designed to power electronic devices. It works on a peak current mode control architecture to ensure accurate and efficient voltage regulation over a wide range of input and output voltages. The device can be configured to operate in a wide range of topologies, including buck, boost, buck-boost, and buck/boost-flyback. With its highly integrated features and its high efficiency for short and medium term applications, it makes a great choice for many applications.The L6984TR implements a power factor correction (PFC) circuit for improved efficiency in mains powered applications. The PFC circuit reduces input power dissipation and improves power system performance. The device has a wide range of operating temperature ratings from -40°C to 105°C and can operate up to 150kHz and 2.5A of output current.The L6984TR operates on a single 5V or 3.3V power supply, providing an adjustable output voltage ranging from 0.9V to 5V. It has a full complement of protection features, including under-voltage lockout, over-current protection, short-circuit protection, and thermal shutdown with hysteresis to protect against current surges and over-temperature conditions.When designing with this device, the user must consider input power, peak current mode control, components, characteristics of the output voltage, power dissipation, and the behavior of the output protection circuitry.The L6984TR utilizes peak current mode control to accurately control output voltage or current. Peak current mode control has a fast response time and provides the advantage of controlling the current and allowing the voltage to follow. This makes it ideal for battery-powered or fast load transients applications.The user must also consider the characteristics of the output voltage, such as the line, load, and temperature regulation, ripple, and output impedance. The line regulation is the change in output voltage with a change in input voltage. The load regulation is the change in output voltage with a change in load current. The temperature regulation is the change in output voltage with a change in temperature. The ripple is the AC component of the output voltage. The output impedance is the resistance between the output and ground of the regulator.The power dissipation of the L6984TR must also be taken into consideration. The total power dissipation of the device is the sum of the output power and the power dissipation across the power FET. The power dissipation of the device is proportional to the output power of the device, the input voltage, and the output voltage.Output protection circuitry is also present in the L6984TR. The device includes under-voltage lockout, over-current protection, short-circuit protection, and thermal shutdown with hysteresis circuitry to protect against current surges and over-temperature conditions.In summary, the L6984TR is a highly integrated switch mode voltage regulator with peak current mode control, integrated PFC, and high efficiency. It can be configured to operate in a wide range of topologies, including buck, boost, buck-boost, and buck/boost-flyback. It has a wide operating temperature range and high current capability, with a wide range of protection features. Designers must consider input power, peak current mode control, components, characteristics of the output voltage, power dissipation, and the behavior of the output protection circuitry when designing with this device.
