9 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

9.1 Application Information

The UCC28C4x-Q1 controllers are peak current mode pulse width modulators. These controllers have an

onboard amplifier and can be used in isolated and nonisolated power supply designs. There is an onboard totem

pole gate driver capable of delivering 1 A of peak current. This is a high-speed PWM capable of operating at

switching frequencies up to 1 MHz. Figure 29 shows a typical off-line application.
