The TPS40000DGQR is a high-efficiency voltage regulator designed for controlling non-isolated synchronous DC-DC converters. It features fast-response current-mode regulation, precise voltage regulation, and robust loop dynamic behavior. With a simple external circuit, it allows designers to apply it to a wide range of applications. Its wide range of output voltages, user-configurable parameters, and fast transient response make it suitable for use in applications such as distributed power systems, telecom/networking systems, server systems, and automotive electronics.

The TPS40000DGQR is designed to regulate the output voltage in systems employing synchronous rectification with heavy transient load conditions. It regulates the output voltage by modulating the pulse width of the signal input to the switch-mode converter. This feature allows the controller to provide a fast and precise response to transient loads. Additionally, the TPS40000DGQR provides many additional features, such as programmable frequency, freewheeling time, current limit, and number of pulses.

The TPS40000DGQR features two voltage feedback loops, which allow the regulation of two separated output voltages along with one common reference voltage. This feature allows the device to be used in a wide range of applications, including dual rail output DC-DC converters, as well as applications where two sources of voltage are required.

The TPS40000DGQR is powered by a single supply voltage and can operate from 2V to 20V. It has a programmable operating frequency, adjustable from 500 kHz to 4 MHz, and a selectable duty cycle of 30~90%. The device also features under-voltage lockout (UVLO) hysteresis, over-temperature protection (OTP), and over-voltage protection (OVP) to provide enhanced protection against fault conditions.

The TPS40000DGQR provides high-frequency peak current mode control. This feature allows the controller to sense any small changes in input voltage and respond correspondingly. It also allows the user to decrease the switching frequency and reduce the amount of power used, while still providing excellent voltage regulation.

The TPS40000DGQR is a highly efficient, fast-response voltage regulator designed for controlling non-isolated DC-DC converters.
