Current-mode control provides simple external pensation and flexible ponent 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. VIN 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 94% to 107% of its nominal voltage. A wide switching frequency range allows efficiency and external ponent size to be optimized. Frequency fold back and thermal shutdown protects the part during an overload condition. The TPS54060 is available in 10-pin thermally enhanced HVSSOP Power PAD™ package and 10pin 3-mm × 3-mm VSON package.
