The TPS54160A device is a 60-V, 1.5-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 output supply current to 116
μA. Using the enable pin, shutdown supply current is reduced to 1.3 µA.
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/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.
