TPS54260DGQR

The TPS54260 device is a 60-V, 2.5-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 138 μA. Using the
enable pin, shutdown supply current is reduced to
1.3 μA, when the enable pin is low.
Undervoltage lockout (UVLO) is internally set at
2.5 V, but can be increased using the enable pin. The
output voltage startup ramp is controlled by the slowstart pin that can also be configured for sequencing
and tracking. An open-drain powergood 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 foldback and thermal shutdown protects
the part during an overload condition.
The TPS54260 is available in 10-pin thermally
enhanced MSOP and 10-pin 3-mm × 3-mm SON
PowerPAD packages.
