Application Field:

• Consumer electronics
• Industrial applications
• Telecommunications equipment
• Computer power supplies
• Automotive systems

Working Principle:

The UCC3813D-1G4 works on the principle of pulse width modulation or Pulse Width Modulation (PWM). PWM is a method of modulation in which the duty cycle of a signal is varied to control the power output. In terms of DC–DC switching controllers, this is accomplished by controlling the switch on and off times, thus controlling the average voltage to the load. The UCC3813D-1G4 includes an internal error amplifier, which monitors the output voltage of the system and adjusts the on and off times of the transistor to maintain the desired output voltage. The maximum duty cycle and frequency of the switching can be adjusted, allowing the system to balance the power efficiency and EMI performance.

The UCC3813D-1G4 also includes integrated high and low-side MOSFETs, and an adjustable leading-edge blanking for optimized EMI performance. The integrated power MOSFETs reduce the bill-of-material costs, and improve the efficiency of the system. The adjustable leading-edge blanking allows you to optimize the EMI performance of the system by adjusting the timing of the switch on and off times.

In conclusion, the UCC3813D-1G4 is a cost-effective, low power DC–DC switching controller that is suited for a wide range of applications. It includes an on-board MOSFET switch, integrated power MOSFETs, and adjustable leading-edge blanking. The adjustable maximum duty cycle and frequency of the switch allow you to balance the power efficiency and EMI performance of the system. The UCC3813D-1G4 is ideal for applications that require high performance and low costs.
