Product Description

The TPS54240QDGQRQ1 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 is internally set at 2.5V, but can be increased using the enable pin. The output voltage start-up ramp is controlled by the slow-start pin that can also be configured for sequencing/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.
High efficiency at light loads with a pulse-skipping Eco-mode™ control scheme
Synchronizes to external clock
Adjustable slow start/sequencing
Undervoltage and overvoltage power-good output
Adjustable UVLO voltage and hysteresis
Supported by SwitcherPro™ software tool
