Product Overview

The TPS54040DGQ 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 116µA. 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 startup 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 93 to 107% of its nominal voltage. A wide switching frequency range allows efficiency and external component size to be optimized. Frequency fold back and thermal shutdown protects the part during an overload condition.
  • High efficiency at light loads with a pulse skipping Eco-mode™
  • Synchronizes to external clock
  • Adjustable slow start/sequencing
  • Undervoltage and overvoltage power-good output
  • Adjustable UVLO voltage and hysteresis
  • Supported by SwitcherPro™ software tool
  • 200mR High-side MOSFET
  • 116µA Operating quiescent current
  • 1.3µA Shutdown current
  • 0.8V Internal voltage reference
  • Green product and no Sb/Br
