The TPS6372-DRCR is a less-than-3-mm-packaged synchronous rectified step-down DC DC converter. It is a single-inductor, single-capacitor (L-cap) buck converter with an integrated high-side MOSFET and is used in a wide variety of applications in the industrial and consumer markets, including DC-DC non-isolated buck power converters, point-of-load (POL) powering, distributed powering and LED lighting. This device is specifically designed to provide tightly regulated output voltages and high efficiency at a wide range of load current values.

The TPS6372-DRCR is in the category of DC-DC Switching Regulators. This type of regulator converts a dc input voltage to a dc output voltage that can be better regulated than a linear regulator. The regulator consists of an input voltage, a switch, an inductor, a capacitor and a control circuit. When the switch is closed, the input voltage causes current to flow through the inductor, creating a magnetic field. When the switch is opened, the inductor current and magnetic field are dissipated into the capacitor, creating the desired voltage at the output. This process is referred to as a “charge pump” and is used to regulate the output voltage.

The control circuit in the TPS6372-DRCR compares the output voltage to a reference voltage, and turns the on-chip switch on and off at a high frequency to maintain the output voltage. The frequency of oscillation is determined by the operating conditions, such as the output voltage, load current, and input voltage. The switching frequency can be up to 500kHz. The device includes a complete frequency stabilization network (FSN) that is used to guarantee an even switching frequency, independent of board layout or other components on the board.

The main application areas for the TPS6372-DRCR are point-of-load powering, distributed powering, LED lighting, lighting and power applications in industrial, medical, communication and consumer electronics, and adapter and charger applications. The device is also suitable for step-up/step-down power supplies and battery management systems, as well as other applications that require high efficiency, small size, and low output voltage.

The TPS6372-DRCR offers several features that make it an ideal choice for many applications. It includes a soft start function that limits inrush current and interference during startup, enabling noise-sensitive operations. The device also includes integrated fault protection with short-circuit, over temperature and load overload protection, making it an ideal choice for robust applications. The device also offers programmable over voltage protection that provides an additional safety margin to the system.

In addition, the TPS6372-DRCR is a high-performance device, with a wide input voltage range, up to 42V, and wide operating temperature range from -40°C to 125°C, making it suitable for industrial applications. The integrated protection and power good functionality of the device also add value to system design.

In summary, the TPS63700DRCR is a single-inductor, single-capacitor buck DC-DC regulator with high efficiency and a wide range of features. It is an ideal choice for applications that require an output voltage between 0.8V and 5.5V and is particularly suitable for point-of-load powering, distributed powering and LED lighting. The high-efficiency and wide temperature range, together with integrated protection, make it a great choice for industrial and consumer applications.
