TPS40130RHBT Application Field and Working Principle

The TPS40130RHBT is a PMIC (Power Management IC) voltage regulator that uses DC-DC switching controllers to regulate the output power of the device. It is designed to provide a regulated, high efficiency output with minimal component count by utilizing a novel architecture that includes a Constant On-Time (COT) control scheme. The TPS40130RHBT is suitable for use in various applications including telecom, embedded products, automotive, and mobile systems.

The TPS40130RHBT is designed to provide a cost-effective, low component count solution for efficient power conversion. It utilizes an advanced COT controller that allows for high-efficiency operation over a wide range of load conditions and input voltages. The device integrates two MOSFETs for high-current switching applications. The device also provides protection features such as undervoltage lockout (UVLO) and overvoltage protection (OVP).

The TPS40130RHBT uses a constant on-time (COT) control scheme. This COT scheme regulates the power output through continuous monitoring of the voltage supplied at the output of the device. When the output voltage drops, the on-time of the MOSFET decreases and the power supply is shut off until the output voltage returns to its nominal value. During overvoltage, the on-time is increased until the output voltage again returns to the desired voltage.

The TPS40130RHBT utilizes an adjustable soft-start, which enables the device to start up without too large of a surge. During soft-start, the duty cycle of the MOSFET is ramped from zero to the programmed duty cycle. This ramped duty cycle helps reduce the in-rush current and reduces stress on the output v/s source components. Additionally, for applications that do not require a soft-start, the soft-start feature can be disabled.

The TPS40130RHBT is designed to provide protection to its output. The device has built-in overvoltage protection (OVP), which will shut off the output when the voltage rises above a predetermined threshold. Additionally, the TPS40130RHBT has undervoltage lockout (UVLO) which protects the output from damage caused by too low of a voltage. The device also features a thermal shutdown feature, which will shut off the output when the device temperature exceeds the rated temperature.

The TPS40130RHBT is a cost-effective solution for efficient power conversion. It is suitable for use in a variety of applications, including telecom, embedded products, automotive, and mobile systems. The device utilizes a unique COT architecture and integrates two MOSFETs for high-current switching applications. Additionally, it offers various protection features for added protection to the output. With its low component count and flexible design, the TPS40130RHBT is an ideal solution for efficiently regulating the output power of electronic applications.
