3 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.
Undervoltage 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 MSOP10 PowerPAD package.
