The TPS54160DGQ is a 60V 1.5A Step-down Converter with an integrated high-side MOSFET and Eco-mode™. 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. Under-voltage 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 fold back and thermal shutdown protects the part during an overload condition.
