1.4 Device Information

The high-side and low-side MOSFETs are incorporated inside the TPS543B25T thermally enhanced package along with the gate-drive circuitry. The low drain-to-source on-resistance of the MOSFET allows the TPS543B25T to achieve high efficiencies and helps keep the junction temperature low at the rated output current. Fixed frequency advanced current mode control allows you to synchronize the regulators to an external clock source. An external divider allows for an adjustable output voltage. The TPS543B25T FSEL and MODE pins provide selectable switching frequency, soft-start time, current limit, and internal compensation. Lastly, the TPS543B25T includes an enable pin and a power-good output, which can be used for sequencing multiple regulators.
