The W83310SG TR is a voltage regulator designed for special purposes, allowing engineers to regulate low output voltages to specific levels that other regulators cannot achieve. The device offers consistent performance and is designed for high power requirements, as well as offering a wide range of voltage, current and temperature ratings.

Application Field

This device has been designed for a wide range of applications including those that require high power regulation, such as those related to aircrafts, industrial machinery, radio communication and power supplies. The device has a wide voltage range of 0 V to 14 V and is capable of regulating low output voltages, such as -5 V, to specific levels.

The device is suitable for use in battery-powered applications due to its low current consumption and operation even at very low battery voltages. Additionally, it offers the highest level of performance when used in environments requiring a wide temperature range. As such, it is ideal for industrial or automotive applications.

Working Principle

The W83310SG TR is a buck voltage regulator, meaning it drops the input voltage before it is passed to the output. Its internal switching frequency can be programmed from 200 kHz to 600 kHz, making it suitable for a broad range of applications. The regulator incorporates a programmable voltage ramping feature, allowing it to smoothly transition from one regulated voltage to another, reducing the risk of inrush current or other disturbances.

The device offers high efficiency at a wide range of output power levels up to 3 A and accepts an input voltage of 3 V to 28 V. The output voltage range is adjustable from 0.8 V to 5 V, meaning it is suitable for regulating a wide range of output powers. Additionally, the device allows the output voltage to be set externally or via a digital signal, giving users flexibility and precision when regulating the output voltage.

Its integrated under-voltage lockout feature prevents the output voltage from falling below its rated voltage, protecting against out-of-regulation conditions. Additionally, the W83310SG TR features integrated soft-start, ensuring that the output voltage is ramped up slowly when the device first powers up. This allows the output power to be regulated slowly, reducing inrush current in the system.

Conclusion

The W83310SG TR is a versatile voltage regulator designed for high power requirements and for use in applications that require wide temperature ranges, such as aircrafts, industrial machines, and radio communication and power supplies. It can regulate low output voltages to specific levels, making it suitable for a variety of applications. The integrated under-voltage lockout feature prevents output voltage from falling, while the included soft-start feature prevents inrush current in the system.
