TPS61006DGSR Application Field and Working Principle

TPS61006DGSR is an energy efficient, single-phase step-down converter for Post Regulation in the area of industrial and automotive applications. TPS61006DGSR was developed by Texas Instruments and it falls in the category of PMIC - Voltage Regulators - DC DC Switching Regulators.

Overview of TPS61006DGSR

The TPS61006DGSR solutions are optimized for industrial, medical and automotive applications, such as HVAC, Lighting, Motor driving, Sensor Activation, and White Goods, where post-regulation is used. The TPS61006DGSR offer a 6 A high current capability and excellent efficiency with full load and low-load conditions, which allows them to be used in applications with wide throughputs, such as Post-regulation from a non-isolated DC/DC converter to provide additional power supply stability and accuracy.

Features and Benefits of TPS61006DGSR

The TPS61006DGSR solutions offer low noise operation, allowing the use of sensitive electronics, and are equipped with a step-start and thermal regulation scheme, allowing them to be used in a wide temperature range and a wide input voltage range. Additionally, they allow operation conditions to be customized to specific applications, simplifying the design process. Other benefits include fast loop transition, as well as near zero input current ripple, efficient light load performance, and an internal soft start feature to reduce the output inrush current and provide an orderly startup.

Working Principle ofTPS61006DGSR

The TPS61006DGSR is a current mode switching converter. It uses a voltage-controlled oscillator (VCO) to drive an internal power switch, which is connected to the output via an inductor and a diode. The voltage on the output is regulated by controlling the duty cycle of the switch, and the output current is regulated by controlling the current through the internal switch. The operating frequency of the oscillator is typically set by an external resistor. This architecture allows for fast current-mode control, even at very low output voltage.

The TPS61006DGSR uses a synchronous rectifier to enhance efficiency at light-load and no-load conditions. When the switch is turned off, the energy stored in the inductor is transferred to the output through the synchronous rectifier, helping to improve efficiency when the output load is light. At no-load conditions, the VCO can cause the output voltage to drop to a pre-determined level, which helps to prevent parasitic load currents.

Conclusion

This article discussed with TPS61006DGSR application field and working principle, which falls in the category of PMIC - Voltage Regulators - DC DC Switching Regulators. With excellent efficiency with full load and low-load conditions, high current capability, low noise operation, fast loop transition and zero input current ripple, TPS61006DGSR is a high-performance and energy-efficient solution for post-regulation in industrial, medical and automotive applications.
