The TPS40004DGQR is a dual 4-phase synchronous buck converter developed by Texas Instruments. It is part of their POWERPAD family of DC-DC controllers. This device provides two 4-phase buck converters that can be used together or separately for a wide range of applications. With up to 200 mV of ripple at the output, the TPS40004DGQR enables efficient, high performance DC/DC conversion. The device has a wide operating range of 4.5 V to 18 V and is capable of delivering up to 50 A of continuous output current at each of the two outputs.

The TPS40004DGQR is part of the PMIC – Voltage Regulators – DC DC Switching Controllers group. Its operation is based on a two-stage power conversion process which combines an input voltage regulator and a non-inverting synchronous buck converter Stage. Both stages establish a regulated output voltage at the DC bus of the controller. This regulated voltage is then regulated further by an output voltage regulator. The TPS40004DGQR is configured through a range of selectable voltage settings, current limits and fault protection features, allowing it to be adapted to suit a variety of application requirements.

With its low output ripple, high efficiency and low quiescent current, the TPS40004DGQR is ideally suited for high-current applications such as servers, storage and networking, FPGA and ASIC power solutions, and high-performance systems. It is also suitable for applications in power control and system management, such as processors and graphics, industrial, automotive and telecommunication.

The TPS40004DGQR is also extremely versatile, operating in continuous conduction mode, discontinuous conduction mode, and even burst mode operation. It also supports adjustable switching frequency, duty cycle and output voltage to optimize the performance of the converter. Additionally, it has excellent thermal performance and independent fault protection, making it an ideal choice for system designers who require the highest performance and reliability.

The TPS40004DGQR is a powerful and reliable buck converter with excellent efficiency, low ripple and fast transient response. Its wide range of features, configurability and adjustable parameters makes it the ideal solutions for a variety of high current applications. Furthermore, its robust construction and ultra-low quiescent current make it an ideal choice for designers requiring a high-performance, reliable and efficient DC/DC converter.
