The TPS54040A device is a 42 V, 0.5 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 input supply current to 116 μA. Using the enable pin, shutdown supply current is nominally 1.3 μA when the enable pin is low. Under voltage lockout is internally set at 2.5 V, 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 or tracking. An open drain power good signal indicates when 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 fold back and thermal shutdown protects the part during an overload condition.
