3 Description

The TPS54060A device is a 60V, 0.5A, 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 116μA. Using the

enable pin, shutdown supply current is reduced to

1.3μA, when the enable pin is low.

Under voltage lockout is internally set at 2.5V, 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.
