3 Description
The TPS57060-Q1 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. When the
enable pin is in the low state, the shutdown current is
reduced to 1.3 μA.
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 and
tracking. An open-drain power good signal indicates
the output is within 92% to 109% of the 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 TPS57060-Q1 device is available in a 10-pin
thermally enhanced MSOP-PowerPAD™ package
(DGQ) and a VSON (DRC) package.
