JAJSPW0B June 2023 – June 2024 TPS543B25T
PRODUCTION DATA
The TPS543B25T employs advanced current mode control (ACM) architecture to provide internal feedback loop compensation for most applications. By applying VIN, duty cycle, and low-side FET current information to generate an internal ramp combined with contribution from internally sensed inductor valley current, ACM cancels one of the poles of the output LC filter and provides phase compensation to make sure of loop stability. As with any internal compensation scheme, certain design guidelines must be followed. Guidelines for a converter design are provided in the following sections.
