Introduction

The TPS650830ZCGR is a 6-channel low-dropout (LDO) voltage regulator in the special purpose portfolio of Texas Instruments\' Power Management ICs (PMICs). Designed for a wide range of applications, it provides efficient, low-noise and low-volatility power supply solutions. This article will provide an overview of the TPS650830ZCGR’s application field and working principle.

Application field

The TPS650830ZCGR provides low-noise and low-volatility power supply solutions for various applications, including industrial control systems, digital audio/video equipment and portable electronics. The LDO offers a wide input voltage range of 4.75V to 22V and adjustable output voltages as low as 1.8V with a programmable current range of up to 500mA. It\'s worth noting that the TPS650830ZCGR has a low-EOS (End of Step) of 150 mV, which helps reduce power consumption in switching power supplies.

Working Principle

The TPS650830ZCGR is a 6-channel low-dropout linear regulator with a wide operating range from 4.75V to 22V. It has a programmable current limit of up to 500mA with an adjustable output voltage of 1.8V to 18V. The device requires a minimum of 7V for regulation, allowing for a wide input voltage range.The TPS650830ZCGR incorporates a unique architecture that uses two voltage ranges to regulate output voltage with a linear topology. When the input voltage is greater than the lower threshold voltage, the TPS650830ZCGR operates in the high range mode, providing a low EOS (end of Step) voltage of 150mV. When the input voltage is less than the lower threshold voltage, the TPS650830ZCGR switches to the lower range mode to maintain the desired regulated output voltage. The TPS650830ZCGR also has output voltage tracking and adjustable integrated soft start for controlled in-rush current during power up.The TPS650830ZCGR has an internal overvoltage protection (OVP) circuit with adjustable OVP threshold voltage. It also has a debounce circuit to guarantee output voltage accuracy. In addition, the device contains an open drain error flag pin to indicate an output voltage fault.

Conclusion

The TPS650830ZCGR is a 6-channel low-dropout linear regulator with a wide operating range from 4.75V to 22V. It has a programmable current limit of up to 500mA with an adjustable output voltage of 1.8V to 18V and a low EOS of 150 mV, making it an ideal choice for industrial control systems, digital audio/video equipment and portable electronics. In addition, it also features an internal overvoltage protection circuit, a debounce circuit, and an output voltage tracking circuit, making it a highly reliable and efficient solution for powering various applications.
