The UCC3801PWTR is a monolithic full-bridge DC/DC converter controller. It is part of the Analog Devices Power by Linear™ family and is used for applications requiring high current power demand for a control interval. The part is sold in an 8-pin DIP package and 8-pin SOIC package.

The UCC3801PWTR is well suited for switch-mode power supplies in a variety of applications. It features a current-mode architecture with stability and protection circuits that make it ideal as a high-performance solution for a wide range of applications. The device can be used as either a buck, boost, or full-bridge DC/DC converter.

The UCC3801PWTR is designed to efficiently convert a wide range of input voltages (2.5 V to 44 V), and provides an adjustable output voltage of up to 50 V. It is capable of delivering up to 4 A peak output current. The device also features an adjustable load-line voltage that can be programmed via external resistors. The UCC3801PWTR also provides programmable soft-start and over-voltage protection options.

The device features an insulated start-up/shut-down input, as well as a dedicated logic shutdown output. The logic shut-down can be used for controlling the on/off state of the device, as well as for diagnostics.

The UCC3801PWTR is a current-mode switching controller that combines the functions of a buck, boost, and full-bridge converter in a single device. This makes it suitable for a variety of applications, from buck/boost converters, to full-bridge applications. The device works in either a constant-frequency or pulse-skip frequency mode.

The UCC3801PWTR supports a wide range of operating modes and voltage configurations. It also has an adjustable deadtime control and current limit, which provide protection against both over-currents and over-voltage conditions. In addition, the device can be programmed to operate in a variable-frequency operation mode, which allows it to run at different frequencies in order to reduce noise and EMI.

In the constant-frequency mode, the UCC3801PWTR uses a synchronization input to provide an exact fixed frequency for the output voltage. The device also incorporates a unique “burst-mode” operation that allows the device to operate at a lower frequency during light-load conditions, providing increased efficiency.

The UCC3801PWTR features a remarkably low-noise design, with integrated noise-shaping features and careful matching of internal components. This allows the device to deliver a low-noise, high-efficiency signal to the output. It also can be used for applications that require constant frequency, but with low-noise output.

The UCC3801PWTR is a highly efficient, low-cost, and low-noise solution, making it ideal for a wide range of applications. It is designed to be compatible with either a discrete MOSFETs or a zero-voltage switching device, and can be implemented in applications with an input voltage range from 2.5 V to 44 V, and an output voltage of up to 50 V.
