The TPS54260-Q1 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.
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 and tracking. An open drain power good signal indicates the output is
within 94% to 107% 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
The TPS54260-Q1 is available in 10-pin thermally-enhanced HVSSOP and 10-pin 3-mm × 3-mm
