Texas Instruments’ TPS62000DGSG4 voltage regulator is a power device meant for a variety of applications. It is classified as a DC-DC switching regulator, meaning a switching circuit is used to regulate input and output power. In this device, a programmable output voltage is available from the output pins where the duty cycle of the switching circuit is controlled.

The applications for this DC-DC switching regulator are wide-ranging, from computing to communication and imaging and other data processing. It can be used as a system power source for these applications, as well as for voltage conversion and power stabilizing for data base and networking.

The functional principle of this device is a programed voltage conversion at the output pins of the regulator. Through the controlling circuitry, input voltage is converted to a regulated output voltage with a set accuracy. The output of the device is kept constant by a closed-loop circuit that detects and regulates voltage feedback.

The TPS62000DGSG4 device integrates a push-pull circuit with a low resistance switch that can accept input power in the range of 3 – 17 Vdc and have output voltages ranging from 0.6-5.5 Vdc. The device can deliver power up to 1.5A and is available in the following packages: the DFN10L-3×3, the W-CSP9L-4×4, and the 3-mm×3-mm VQFN10.

The internal circuitry also includes a power sense amplifier for improved accuracy and switching voltage control. It also features a programmable switching frequency, adjustable output voltage, and pulse-skipping mode or power save mode, which requires lower switching frequency. In this power save mode, the amount of heat generated by the device is reduced.

The TPS62000DGSG4 has several built-in protection features to help prolong its life, such as input overvoltage protection, thermal shutdown, and frequency foldback. It also has an internal 5 ms soft start function and an operational junction temperature range of -40 °C to 125 °C.

To sum up, the TPS62000DGSG4 is a DC-DC switching regulator from Texas Instruments suitable for a wide range of applications from computing to communication, imaging, and data processing. It provides a programmable output voltage and can accept input voltage in the 3 – 17 Vdc range with an output voltage ranging from 0.6 – 5.5 Vdc. Its integrated circuitry includes an internal look-up-table and power sense amplifier for improved accuracy and switching voltage control. It comes with several protection functions and is available in 3 different packages.
