The UCC3807DTR-3 is an asynchronous step-down DC-DC integrated circuit used as a power supply controller. It is part of Texas Instruments\' family of DC to DC switch controllers and belongs to the PMIC (Power Management Integrated Circuits) Voltage Regulators DC DC Switching Controllers. This device offers users the necessary performance for their intermediate supply applications such as reliable and adaptable core voltages for DSPs and FPGAs.
The UCC3807 includes a dedicated 700mA peak current boost mode switch. With up to 95 percent efficiency and very low quiescent can operate over a wide input voltage range from 4V to 14V and provide output voltages from 0.6V to 0.9V. It is configured for feedback voltage regulation for applications including FPGA supplies, DSP core supplies, processor core voltage switching, and static memory supplies on analogue converters. It is available in a 5x5mm VQFN package.
The working principle of the UCC3807DTR-3 is based on Pulse Width Modulation. It has two independent current-mode control loops which enable a fast, accurate regulation of the output voltage while maintaining a high conversion efficiency. The integrated boost mode and proprietary current-mode PFM provide fast transitions with high accuracy and provide a wide range of regulating output voltages, current limitations and features to support and optimize system performance.
The main features of the UCC3807DTR-3 include:
- Compatible with PWM, PWM/PFM hybrid, and PFM modes
- Integrated boost mode switch
- Slew rate controlled soft-start
- 4V-14V input range
- Programmable digital soft-start
- Over-temperature, over-voltage and over-current protection
- Integrated FETs
The UCC3807DTR-3, with its high efficiency, provides a cost-effective solution to core voltage regulation applications. The device’s small footprint makes it ideal for space-constrained designs. Low quiescent current and the ability to operate over the entire input voltage range make it a good choice for powering a wide range of loads.
In conclusion, the UCC3807DTR-3 is an integrated DC-DC switch controller which belongs to the PMIC Voltage Regulators DC DC Switching Controllers family. It features robust protection mechanisms, very high efficiency and a wide range of output voltages and current for various applications including DSPs and FPGAs. Low quiescent current, small package size and wide temperature range makes it a great choice for power supply designers.
