It is an integrated device that includes a winding compensation comparator, gate drive, reference, and error output. It has a wide operating temperature range from -40°C to +150°C. The UCC3800DG4 is well suited for a variety of DC-DC conversion applications such as buck, boost, flyback, and push-pull configuration.

Overview of UCC3800DG4 Applications

The UCC3800DG4 is ideal for a wide variety of DC-DC applications. It can be used in buck, boost, flyback, and push-pull configurations. In addition, the device can be used to convert a wide range of input voltage levels to both positive and negative output levels. Because it is capable of supporting pulse-width-modulated (PWM) and pulse-frequency-modulated (PFM) control, it can be used in applications from small low-power to large high-power applications. It includes several features that make it the ideal choice for applications such as boost-backup, buck-boost, forward, inverting, and bi-directional converters.

Technical Specifications of UCC3800DG4

The UCC3800DG4 is a low-power synchronous DC-DC controller with several features. Its maximum operating current is 2A, and its maximum operating voltage is 20V. It is rated for a maximum switching frequency of 500kHz. The device also includes a minimum on-time of 100ns, a typical shutdown current of 1µA, and a maximum operating temperature range of -40°C to +150°C. The UCC3800DG4 can also operate in both pulse-width-modulated (PWM) and pulse-frequency-modulated (PFM) control modes.

Working Principle of UCC3800DG4

The UCC3800DG4 is a DC-DC controller which works by using MOSFETs to perform voltage conversion between two different portions of an electrical system. It does this by first taking a DC input voltage, converting it to an AC signal, and then feeding the AC signal to an output filter where it is then converted back to a DC voltage. The UCC3800DG4 is capable of operating in either pulse-width-modulated (PWM) or pulse-frequency-modulated (PFM) control modes. In PWM mode, the switching frequency is controlled by compensators and an internal reference voltage. The frequency can be varied to optimize power conversion efficiency. In PFM mode, the switching frequency is not controlled and is instead fixed at the maximum operating frequency.

The UCC3800DG4 also includes a winding compensation comparator and gate drive. The winding compensation comparator is used to detect the inductor current of the output filter and to feed it to the gate drive. This is important because the gate drive controls the opening and closing of the power MOSFET to switch the DC-DC converter. The UCC3800DG4 also includes an error output to monitor the output voltage and current of the converter.

Conclusion

The UCC3800DG4 is a mid-voltage synchronous DC-DC controller that can be used in a variety of applications. It is ideal for buck, boost, flyback, and push-pull configurations, as well as for applications from small low-power to large high-power applications. The UCC3800DG4 is capable of supporting pulse-width-modulated (PWM) and pulse-frequency-modulated (PFM) control, and includes a winding compensation comparator, gate drive, reference, and error output.
