TPS54260DRCT

The TPS54260DRCT is a Step-down Regulator with an integrated high-side MOSFET. Current-mode control provides simple external compensation and flexible component selection. A low-ripple, pulse skip mode reduces the no load, regulated output supply current to 138µA. Using the enable pin, shutdown supply current is reduced to 1.3µA, when the enable pin is low. Undervoltage lockout (UVLO) is internally set at 2.5V, but can be increased using the enable pin. The output voltage startup ramp is controlled by the slow-start pin that can also be configured for sequencing and tracking. An open-drain power good signal indicates the output is within 94 to 107% of its nominal voltage. A wide switching frequency range allows efficiency and external component size to be optimized. Frequency foldback and thermal shutdown protects the part during an overload condition.
