TPS62052DGSR is an integrated power solution developed by Texas Instruments. As part of the family of DC-DC switching regulators, this product offers a highly efficient point-of-load voltage regulator in a low-profile Thin SON package. The TPS62052DGSR regulates step-down 4.5 V to 44 V input voltages, producing 0.8 V to 6 V output voltages with up to 4A output. With its high integration, low quiescent current, and wide input voltage range, the TPS62052DGSR is well suited for a variety of applications including digital TV, telecom, networking, industrial, computing, and automotive.

The basic principle of operation of the TPS62052DGSR is similar to many other DC-DC switching regulator devices. When the input voltage is applied, a basic internal comparator measures the difference between the input voltage and a reference voltage. If the input voltage is greater than the reference voltage, the IC triggers a gate drive signal to the compatible metal-oxide-semiconductor field-effect transistor (MOSFET). This allows the output voltage to commence regulation. As the output voltage is being regulated, the IC measures the output voltage and gives feedback using its error amplifier. This feature allows the output to be adjusted or corrected anytime the set value has been disturbed due to load changes or other effects.

The TPS62052DGSR is suitable for a variety of applications including those in the industrial, computing, communications, automotive and consumer electronics markets. The device features a low quiescent current (typ. 23 μA) and is capable of providing output voltages with efficiencies greater than 91%. Additionally, the buck converter is able to handle nominal input voltages from 4.5 V to 44 V, making it ideal for use with low-voltage batteries, point-of-load regulation, and distributed power systems. With its low noise and high efficiency, the TPS62052DGSR can be used in a wide range of applications including FPGA, DSP, P6502, and Opteron, and AMD CPUs.

The TPS62052DGSR has been designed to provide outstanding performance, with features such as differential remote sensing, adjustable soft-start, and over-voltage, over-current and over-temperature protection capabilities. By implementing an OVP sensor and a dynamic current foldback mechanism, the device can offer excellent load transient response, load regulation, and line regulation. The IC also has a programmable switching frequency range of 200 kHz to 3 MHz and an adjustable soft-start of up to 1ms.

Overall, the TPS62052DGSR is an integrated power solution that is suitable for a variety of applications, offering excellent performance at low quiescent current, high efficiency, and great transient response. As part of the family of DC-DC switching regulator devices, the TPS62052DGSR is a highly efficient point-of-load voltage regulator in a low-profile Thin SON package, capable of handling nominal input voltages from 4.5V to 44V and generating output voltages from 0.8V to 6V with up to 4A of output current.
