DESCRIPTION
The TPS54060 device is a 60-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 output supply current to 116 μA. Using the enable pin, shutdown supply current is
reduced to 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/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.
The TPS54060 is available in a 10-pin thermally enhanced MSOP PowerPAD™ package (DGQ) and a 10-pin
SON package (DRC).
